Tiny Habits summary

Can you imagine cooking a healthy, balanced meal each night? How about also writing a daily entry in a gratitude journal and going out for a run every morning? If the idea of adopting multiple new habits like these seems difficult, there’s help at hand. 

Here’s the key message in this blink: If you want meaningful long-term change, start small. 

You probably already know that to change your life, you have to change your behavior. What you might not know is that there are only a couple of factors that determine whether or not you’ll succeed. 

The key message in this blink: Three key variables drive human behavior – motivation, ability, and prompts. 

Did you know that over 100 million people enroll in online courses every year, but just 10 percent of them graduate? The other 90 percent drop out. Why? For the same reason that people accumulate unused gym passes in their wallets and dusty vegetable juicers in their basements. They got caught in a common human mind trap: they overestimated the power of motivation alone. 

And that’s the key message here: Motivation may suffice for one-off feats, but it’s not enough for sustained change.

When Instagram launched back in 2010, its founders already knew that people were motivated to post photos of themselves online. But no one else had focused on the second variable of behavior: ability. And that’s what set Instagram apart. Taking, uploading, and posting a photo took just three clicks. It was remarkably easy, and people loved the platform for it. Within just 18 months, the company had been sold for $1 billion. Today, it’s worth $100 billion! Simplicity pays off.  

And that’s the key message here: The easier a habit is, the higher the chances that you’ll adopt it. 

Wherever you are, you’re surrounded by prompts that trigger specific responses. Whether it’s the rumble of an empty stomach telling you to eat, or the green traffic light that makes you hit the gas, these prompts announce: “Do this behavior now!” This process is often unconscious – you just do something without giving much thought to why. And this automaticity presents a chance to cement positive changes in your life. 

So what’s the key message here? You can design prompts to trigger your own desired behaviors. 

Like anchors, action prompts stop you from drifting around aimlessly, but you have to be careful where you drop them. The best spots are in routines that you repeat over and over again, day in and day out. These should be the solid rocks among the shifting sandbars of your daily life. And all you need to do now is find them. 

The key message here is: When designing your action prompts, consider location, frequency, and theme.
