The power of habit, Charles Duhigg.

« To understand your own habits, you need to identify the components of your loops. Once you have diagnosed the habit loop of a particuliar behavior, you can look for ways to supplant old vices with new routines.« 

A truly interesting book about how habits work, how they are built and can be transformed for a greater personal or collective good.

I read it to nurture my knowledge in change management for my job but found interesting tips and tricks on a personal level.
