Introduction

According to researchers at Duke University, more than 40% of the actions people perform each day aren't actual decisions, but habits. From how we brush our teeth to how we respond to stress, our lives are largely governed by automatic routines.

In Charles Duhigg's defining book, The Power of Habit, he explains the neurological loop that creates these behaviors and how we can hack it.

The Habit Loop

Every habit consists of three components:

  1. The Cue: A trigger that tells your brain to go into automatic mode and which habit to use.
  2. The Routine: The physical, mental, or emotional behavior itself.
  3. The Reward: The prize that helps your brain figure out if this particular loop is worth remembering for the future.

Pro Tip: You can never truly extinguish a bad habit; you can only overwrite it. To change a habit, you must keep the old cue, deliver the old reward, but insert a new routine.

Keystone Habits

Some habits have the power to start a chain reaction, changing other habits as they move through an organization or an individual's life. These are called "Keystone Habits."

Exercise is a classic keystone habit. People who start exercising often start eating better, become more productive at work, and show more patience with colleagues and family. By focusing on changing just one keystone habit, you can inadvertently improve multiple areas of your life.

Frequently Asked Questions

Should I read physical books or eBooks?

Both have their merits. Physical books are great for deep, distraction-free reading. eBooks are incredibly convenient, allow you to carry an entire library in your pocket, and let you highlight and search text instantly.

How many self-improvement books should I read in a year?

Quality beats quantity. Reading 5 books and deeply implementing their lessons is far better than skimming 50 books. Aim for a pace that allows you to absorb and apply the knowledge.

Are these books suitable for beginners?

Absolutely. The books mentioned in this list are written in a clear, accessible manner and do not require prior knowledge of psychology or behavioral science.
