Atomic Habits is justifiably the 'bible' when it comes to understanding how to build good habits. It's full of strategies to get you where you want to be. Consider it a 7-course gourmet meal in behaviour change.
But who has time for that?
Sometimes you just want to eat and dash! This is why I always recommend The Power of Habit to anyone wanting to take greater control of their lifestyle. It tides you over by providing:
A Simple Explanation
The Power of Habit deconstructs all habits into 3 elements: a cue (hungry), a routine (eat), and a reward (satisfied). Everything we do can be boiled down to this. Modify any element to get a different outcome.
Realistic Solutions
The Power of Habit lists 5 everyday anchors to 'piggy back' new habits onto. These are (a) location, (b) time, (c) emotional state, (d) other people, and (e) immediately preceding action.
An Easy Gateway
