About Change Your Behaviour
You don’t have a discipline problem. You have a design problem. Most of us try to change by trying harder, while the modern world is built to pull us the other way.
Change Your Behaviour translates the behavioural science of habits into a practical system. It draws on Phillippa Lally’s research on how habits form, Wendy Wood’s work on automaticity and BJ Fogg’s work on tiny behaviours.
What you’ll explore
How long habits take. Lally’s study of people forming new daily habits found a median of about 66 days for a behaviour to become automatic, with a wide range between individuals. The book explains what that means in practice.
Cues and environment. Wood’s research shows that much everyday behaviour runs on autopilot, triggered by context. Changing the cues often matters more than motivation.
If-then plans. Implementation intentions, deciding in advance when and where you will act, make follow-through more likely.
Breaking habits. How to stop unwanted habits without relying on white-knuckle willpower.
Designing your surroundings. Making the right choice the easy one.
Making it automatic. Fogg’s work on starting with very small behaviours shows how new routines can become automatic and stay that way.
The book’s message is that behaviour change is not about wanting it more; it is about setting it up right.
Who this book is for
Anyone who has tried to build a habit, or break one, and found that good intentions weren’t enough.
