Habit formation is a THREE step process , this explains..

Adopted from the following great insight shared by Charles Duhigg from the book The Power of Habit

This process within our brains is a three-step loop. First, there is a cue, a trigger that tells your brain to go into automatic mode and which habit to use. Then there is the routine, which can be physical or mental or emotional. Finally, there is a reward, which helps your brain figure out if this particular loop is worth remembering for the future.”
