The following post is a guestpost by Walter Chen, founder of a unique new project management tool IDoneThis. More about Walter at the bottom of the post. 

Ever go through a phase where you feel like every day is a Monday? You wake up, you hit snooze. Then you hit snooze again and you just don’t feel it?

Yes, I know that negative emotions can eat away at my productivity, creativity, decision-making skills. And yet, I have to admit that sometimes it’s really difficult to reverse the course of a slump.

The unfortunate superpower of the negative is that it has a stronger impact than the positive.

In fact negative impact of setbacks in your work is three times as powerful in affecting motivation than positive progress. It’s just easier to remember the bad stuff that has happened to you during the day than the good.

So why is it, that our brains have a such a negativity bias? The reason is quite simple: They’re actually wired to pay more attention to negative experiences. It’s a self-protective characteristic. We are  scanning for threats from when we used to be hunter and gatherers. But such vigilance for negative information can cause a narrowing, downward spiral and a negative feedback loop that doesn’t reflect reality.

Fortunately, we aren’t doomed by our natural disposition towards negativity.  What’s amazing is that we have the ability to break out of that negative feedback loop and we can actually rewire our brains to think positively. Understanding how the brain can refashion its own connections is the key to unlocking the durable power of positive thinking.

And that’s exactly what this post is all about. Let’s dive in:

The Tetris Effect: What it tells us about how our brains learn new things

Anyone who’s ever played the classic, old-school game of Tetris will know this. Whether on a clunky computer or gameboy or the latest mobile device we all know the game’s surreal ability to spill into real life. After you shut off the game, you still see those Tetris blocks falling in your mind’s eye.

You’re grocery shopping, and you find yourself thinking about rearranging items on grocery shelves and carts in the parking lot. Somehow your mind continues to play the game, even when you’re physically not.

Robert Stickgold, Harvard professor of psychiatry, noticed something similar after a day’s hiking a mountain in Vermont. That night, he dreamt that he was still going through the motions of mountain hiking, clinging to rocks. Curious about this dream replay he tried something: Stickgold got a group of college students of varying skill levels to play Tetris and sleep in the Harvard sleep lab.

Over 60% of the study participants (including, surprisingly, those who suffered from amnesia) reported dreams of images of Tetris pieces falling, rotating, and fitting together. Interestingly, half the Tetris expert participants reported such Tetris dreams while 75% of the novices did. The mind was continuing to work on making sense of the game during sleep.

A more recent study from 2009 it was found that playing Tetris can grow your brain and make it more efficient. Adolescent girls played the game for an average of 1.5 hours a week over three months. The cerebral cortex, or the gray matter, of the girls grew thicker while brain activity in other areas decreased compared to when they’d started. Richard Haier, who had previously found in a 1992 study that there was a “Tetris learning effect” in which the brain consumed less energy as mastery of the game rose, concluded,

“[W]e think the brain is learning which areas not to use. . . . As you learn the game, it becomes more automatic.”

Haier’s 2009 study demonstrated how Tetris affected the brain’s plasticity, or the brain’s ability to change structurally, as the girls practiced and learned how to play the game. Neurons, or nerve cells, in your brain make connections, communicating through synapses. When you learn something, you change those neural connections. Every time you reactivate a circuit, synaptic efficiency increases, and connections become more durable and easier to reactivate. Stickgold’s study and subsequent research that sleep plays a role in this memory process.

So to sum up, whenever you do specific tasks over and over again, they take up less of your brain power over time. And that’s pretty amazing, as this will be the basis for a huge opportunity to change our behavior for the better:

So how can we combat our negativity bias? The Positive Tetris Effect.

Indeed, it’s quite simple: We can harness the brain’s plasticity by training our brain to make positive patterns more automatic. When we practice looking for and being more aware of positive aspects of life, we fight off the brain’s natural tendency to scan for and spot the negatives. Naturally we bring ourselves into better balance.

Shawn Achor frames this rewiring as “The Positive Tetris Effect” in The Happiness Advantage, drawing from the way Tetris impresses our brain so that we end up parsing the world in terms of the game. According to Achor, with the positive Tetris Effect,

“we can retrain the brain to scan for the good things in life—to help us see more possibility, to feel more energy, and to succeed at higher levels.”

Yes, so something as trivial as the game of Tetris can have a scientifically measurable effect on people’s brains and invade their dreams. If that’s the case, the impact of practicing and retaining a more positive thinking pattern, especially on our wellbeing and happiness, can be even more powerful.

We are basically trying to find an undiscovered path that if walked once, makes us happy. The path being the synaptic connections in our brain. And then, because we enjoy it, we go along that path, hundreds and hundreds of times. Slowly a track forms and becomes very clear and easier to walk every time.

Here is an example of a synapse, which represents the path we want to go over and over again, to make it a strong, easy to recognize pattern for our brains:

The best thing about such a practice is its long-term effects. In one study, people who did a “three good things” exercise for a week felt happier and less depressed after one month. The study then did the three-month and six-month follow-ups. Not surprisingly, the happiest participants were the ones who had continued the practice throughout.

What this tells me right of the bat is this: There’s hope for us all! (Even for a curmudgeon like me who reacts to the idea of spending time trying to accentuate the positive with a growl.)

So I think a good way to see the positive Tetris Effect like learning a foreign language. It will be the most difficult and unnatural-feeling at the beginning. And yet, the rewards will make you feel unbelievably happier if you stick with it.

4 Awesome Ways to Change Your Life to Be More Lastingly Positive

Ok, now that we’ve been through the background it’s time to get our hands dirty. How can we put all of this into practice?

At the core, the Tetris Effect is about building a habit that becomes more automatic and therefore longer lasting. In turn, this will sustainably boost your productivity and creativity. As Achor notes,

“Happiness is a work ethic . . . . It’s something that requires our brains to train just like an athlete has to train.”

So with that in mind here are some of the top ways that Achor and others identified to rewire your brain for positivity:

  • Scan for the 3 daily positives. At the end of each day, make a list of three specific good things that happened that day and reflect on what caused them to happen. The good things could be anything — bumping into an old friend, a positive remark from someone at work, a pretty sunset. Celebrating small wins also has a proven effect of powering motivation and igniting joy. As you record your good things daily, the better you will get and feel.
  • Give one shout-out to someone (daily). I love this technique and it is also something the Buffer team is using internally. Take the positive things you’re getting better at recognizing and let people know you’ve noticed! Take a minute to say thanks or recognize someone for their efforts, from friends and family to people at work. A great way to go about this is by sending 1 daily email to someone. It can be your old school teacher, who’s advice you are now appreciating every day. A co-worker or someone you’ve only met. Show courage and say thanks, I love doing this and just checking in with a nice note.
  • Do something nice. Acts of kindness boost happiness levels. Something as small and simple as making someone smile works. Pausing to do something thoughtful has the power to get you out of that negativity loop. Do something nice that is small and concrete like buying someone a coffee. You can try and have that even on your to do list – have you done anything nice for someone today? I love this technique and it’s one of the most amazing ways to feel happier.
  • Mind your mind.  Mindfulness is paying attention to the present moment without judgment. Opening our awareness beyond the narrowness of negativity can help bring back more balance and positivity into the picture.

The regular practice of mindfulness meditation has also been shown to affect the brain’s plasticity, increasing gray matter in the hippocampus, an area of the brain important for learning, memory, and emotion, and reducing gray matter in the amygdala, an area of the brain associated with stress and anxiety. Take a look at these tips on mindfulness and meditation to get started.

Over to you now. Have you discovered some of these techniques to focus on creating more happiness for yourself? I’d love your thoughts on this topic.

  • This is brilliant! I am a psychotherapist and have taught these principles to my clients over the years, but this article expands my understanding. I will share it with my clients!

  • A great article, I particularly liked the reference to Shawn Anchor, whose TED talk I would thoroughly recommend everyone watches:

    I don’t usually plug my own work, however, I coincidentally posted my own article on the negativity bias, yesterday. If any of your reader’s are interested, here it is:

    • Very cool article, Jordan. Nice work!

      • Thank you, Walter. Out of curiosity, are there any books on human psychology that you’ve read that you consider worth reading? I’ve not got around to reading Shawn Anchor’s book, have you read it?

  • Frank Klucznik

    The tetris effect mentioned I this article is one of many concepts discussed in Shawn Achor’s book “The Happiness Advantage”.

    The Happiness Advantage is real and tangible; I can attest
    to this from firsthand experience! The book provided me with the repeatable process I use to teach the Happiness Advantage to others. I began by teaching it to my college students, and over the past year have seen it turn peoples’ life around and even benefit entire families who adopted it!

    In fact, I’m so convinced it’s that good that I started a project giving away The Happiness Advantage to strangers as a random act of kindness. Through private funding and the small donations of supporters, we will give away 365 books this year (for FREE) and hope to double that number next year. This is my way of spreading the Happiness Advantage, and helping others with a desire to improve their lives. Check out
    the movement’s website and consider getting involved:

    • That’s great, Frank.

      I give away one book to a reader every month, although I make sure I’ve read the book beforehand, so I can attest to it’s quality. With that said, I’ve been thinking about purchasing The Happiness Advantage.

      • Hey Jordan,

        I bought the happiness advantage and it’s one of the most useful books on happiness that i’ve ever read. It’s actually filled with applicable tactics for making you happier. One my must read list.

        • Thank you for the reassurance @srinirao:disqus

          Just purchased the book on my kindle, now.

          Have you ever read Stumbling on Happiness by Dan Gilbert? The book won’t necessarily make you happier, but it will definitely make you look at happiness in a different light.

  • Nataly

    Great article – thanks for this!

  • flobud

    “over to you “now”, not “know”.. ok?. loved the post! thank you!

  • Raman

    You know walter, I am doing regular meditation, write grateful things at the end of the day and doing act of kindness from quite some time. And my happiness index has increased so much. Now i will add appreciation mail daily after reading this post. Thanks

  • Great article, Walter. I’ve studied some NLP in the past, and this falls in line with that line of teaching. In your experience, how long does it take to completely change a habit?

    • Rhotomago

      30 days is usually the magic number.

  • A great article. It mirrors a few of the techniques I use with clients in business and elite sport. Happiness and performance are linked.

  • Wendy Merron

    Hi Walter, I thoroughly enjoyed your article especially because you have peppered it with great references and research. I learned early on in my career that sometimes the most profound and radical changes happen as a result of simple exercises incorporated into our lives. I’m looking forward to reading more from you.
    P.S. I’m a Board Certified Hypnotherapist 🙂

  • Mary Garner-Mitchell

    Fabulous post above, though I’ve never been much of a gamer. Yes, I had a “kindness epiphany” just this past summer and I blogged about it. See “On living kind” at

  • Tammy Benkwitt

    Thank you for sharing specific and positive ideas. I captured a screen shot to post as my device wallpaper to remind me to do them each day. 🙂

  • Good, I just have to practice, I already started by learning korean!! 😀

  • Hapyr

    We tried to turn this concept into a webapp we’ve released as

  • Karl

    Brilliant article, but why are we so lazy and do not practice when we know it will benefit us!! And it’s free!!!

  • Walter this is a great user friendly article with lots of cited research (Awesome balance). Loved the visuals that were included, as I am a visual learner.This is great practical information for encouraging change in therapeutic situations. Also, I spent lots of time on Tetris as a kid LOL. This is the kind of information that we may sit back and go “Yeah, of course we are like this” it is just good to have someone point it out again so we can do something about it and be “Purposely Positive” about life.

  • Great article. I do a few of the techniques suggested here. I have a Gratitude Book where I write down 10 things I’m thankful for each day. I also practice TM (for the past 18 mos) and I find both practices to be very rewarding. I like the “daily shout out” and be nice initiatives too. I’ll incorporate those as well. Thanks for sharing!

    Happiness is not created, Happiness is the default, Our negative minds and thought and emotions gets us down. Its like a screwed vision of reality. We see things through our mind, so if our mind is faulty, we see our mind faulty vision of the world.

  • remybigot

    Great article, i’m feeling already better after reading it ! I was to much pessimist 10 years agor. Now, i’m so much more positive on everything, and I’m so much happier !

  • Great article. Thanks for sharing! Check out the app called “Happier” in iTunes. It allows you to record three positive things a day and share it with your friends.

  • JakeDK

    Just what i needed right now, thanks!

  • NG

    I’ve been writing down three good things every night for the past seven months, and the difference this has made has been huge. i can really feel that my thinking patterns have changed, and when I do feel down, I am able to see it in perspective and deal with it much more rationally. This really has been a life-changing practice – and also a very enjoyable one. Thoroughly recommended.

  • Felix

    Well written, great ways of expressing which gives a total theory format.

  • christopherdaniel962

    Well written, looking forward for me as I’m a
    reader myself and I almost read the
    entire topics that I have ever come across.

  • christopherdaniel962

    and interesting, great piece of content, above all it is very interesting.

  • Tamar Cerafici

    I’m preparing a talk on gratitude for my church. This lays down nicely with the topic, along with its relation to happiness and appreciation. A gratitude journal is great, but keeping all of that inside minimizes the fun! Letting OTHERS know how lucky you are to have THEM in your life changes the dynamic, and creates an exchange that just keeps going….Even if it doesn’t, who cares? Your cerebellum is firing on all cylinders, the dopamine and serotonin are coursing through your systems, and life is freaking awesome.

  • Michal

    I tried above mentioned technique with much success ! My friends are telling me that a known pessimist turns optimist. Thanks a lot
    Does anybody know about similar technique that would help with keeping focused ? ( I am too much distracted with social media and frequent checking of an email.

    Im wondering if a method i have been using is truly effective to creating a more positive mental outlook. I have been doing something similar to “scan for three positives”. I do it as i lay in bed at night, but i have added in a bit of twist. I fill a tall glass of water up and put it on my night stand. Immediately after writing down or verbally stating aloud 3 things i’m grateful for in my day and their cause, i drink half the glass.(now to sleep)….(upon awaking the following morning) I wake up and make my first active thought(not the hindering thoughts of my dreams) something happy, something that has happened in the past, somebody i’m grateful to have in my life etc. Immediately after i drink the remaining half of cup of water.

    In essence what i was trying to do was attach positive thought to an action that is a basic necessity for me to live. And in doing so I have noticed (its been about 2 months of this practice nightly/daily) that every time i drink water i find myself thinking of a happy memory-being grateful for the little things- and being that its water i’ve begun to associate this with, it happens many times in a given day.

    I wonder if what i’ve done has created a relationship in my mind with drinking water and happiness/happy thoughts/positive thoughts- and rewiring my brain for them, or am i just training myself to actively think of happy when i drink water.(actively but almost to the point of it being so easy it almost happens innately)

    Hopefully someone with some experience in this field of science can give me some insight here.

    Thank you, you’re doing great for the world!
