Updated: Feb 21, 2022

In this post, I explore two of the most popular habit books: Tiny Habits vs Atomic Habits

Both of these books have the potential to transform your life in dramatic ways.

"The outcomes in your life are the lagging measure of your habits - there are no high performance people only high performance habits."

- James Clear Atomic Habits

I first read Atomic Habits in January 2019. I was looking for tips on how to develop better habits. This book literally changed my life.

My physical and mental health improved dramatically.

Fast forward a few years and many of these habits have been sustained.

My success was amplified by reading Tiny Habits in January 2020.

12 months later this reinforced many of the ideas in Atomic Habits.

I've also had great success applying atomic habits in business.

To help you understand the difference between Tiny Habits vs Atomic Habits I share:

💬 The 3 Best Quotes

James Clear Atomic Habits

Habits are the compound interest of improvement."
"Goals are good for setting a direction, but systems are best for making progress."
"Real behavioural change is identity change."

BJ Fogg Tiny Habits

“There are three ways to change behaviour: have an epiphany, change the environment, change habits in tiny ways.”
"Willpower is a myth. Bad habits are due to design flaws, not character flaws."
"If you plant behaviour in the right spot it will grow without coaxing."

Tobys Top Takeaways

Atomic Habits:

Atomic Habits started my passion for building and breaking habits. I've used many of the cheat sheets provided by James Clear to improve my habit systems. For example, the first one I used was the habit scorecard. This helped to identify good, neutral and bad habits based upon my desired identity.

I've also seen huge success applying Atomic Habits ideas in the workplace. In this summary, I expand how you can apply atomic habits in business

Tiny Habits:

Since reading Tiny Habits I have explained the Fogg Behaviour model to 100's of people. The power of the model is its simplicity and application. I've used the model to build tons of new habits. One, in particular, is the habit of writing book summaries. After reading Tiny Habits I used the approach to design a tiny habit: one sentence book summaries. This has now grown to full-blown book summaries you are reading now. This shows the power of planting a habit in the right place and letting it grow.

📗 Conclusion: Which should you read?

Both 😃

But if you could only read one, I would suggest Atomic Habits. The primary reason is James Clears writing style. He expresses complex ideas in clear ways with brilliant stories. His personal story, which he shares at the start of the book, is very inspirational.

At the very least I'd recommend reading my summary of Tiny Habits. Learning the Fogg Behavioural Model is a great complement to Atomic Habits.

I'm reading tiny habits, WHAT A WASTE OF TIME. he kept telling B=MAP in whole book which we know since our childhood(common sense). This book should have been a blog post.. seriously.

(If you have ability and motivation with the cue of the behavior, you will do it.) every chapter is telling you this.. I don't have motivation you fool😡

Brilliant post & thank you for your analysis and take aways.

I read Tiny Habits this summer ( as a speech/language pathologist, working in the public schools with severely delayed children with autism) and it resonated with evidence based research validating my 20 years of behavioral practicum knowledge and educational based knowledge! Then I just listened to Clear with Brene Brown, so clearly articulate the additional takeaways you’ve listed. I say not ”VS” but “AND” regarding these two books. Cheers from Utah!
