Between the Covers: ‘Atomic Habits’ by James Clear (Chapters 16–20)

By Melanie Chance

We’ve reached the end of James Clear’s Atomic Habits, and these final chapters brought the book full circle. They aren’t about quick tricks. They are about going deeper — finding the habits that fit who you are, learning how to stay motivated, and knowing how to keep growing even when life gets repetitive.

In chapter 18, Clear talks about talent and genetics. He says it plainly: some things are easier for us because they fit who we are. “Genes do not eliminate the need for hard work. They clarify it.” That line reminded me that it isn’t about being able to do everything. It’s about figuring out what comes more naturally and leaning into it. We all have strengths, and building habits that align with those strengths increases our likelihood of success.

Chapter 19 introduces the Goldilocks Rule: humans stay motivated when they work on tasks that are not too easy, not too hard, but just right. If something is too simple, we get bored. Too difficult, and we give up. Clear says the key to long-term motivation is finding that middle ground. I thought about how many times I’ve quit too soon because I set the bar unrealistically high, when steady progress would have kept me going.

In chapter 20, Clear ends with a reminder that even good habits can backfire if we run on autopilot. When habits become automatic, we sometimes stop paying attention. That’s why review and reflection matter. He encourages us to build in time to check our progress, to make sure our habits are still serving who we want to become.

These last chapters tied everything together for me. Atomic Habits is not about being perfect. It’s about designing systems, choosing the right environment, leaning into your strengths, and stacking small wins until they add up. It’s about creating a life where your daily habits quietly shape your identity.

Finishing this book left me with one thought: small things aren’t small. They’re everything.

Next month, we’ll start a new journey with a different book, but for now, I hope this one has reminded you, as it did me, that lasting change comes from the little things we choose every day.
