Excellent read. Just finished it today.
Self control is a muscle. It gets tired when you overwork it too much.
ex. Test subjects who are forced to resist eating a cookie will perform far worse in self control & emotional stability compared to their cookie eating coutnerparts.
Habits are formed by the Trigger, Loop, and Reward cycle.
Old habits never die, they are just overrun by new habits.
More often than not, the Triggers cannot be altered. It is best to either completely avoid Triggers or override the Loop & Rewards to form a completely new habit.
Nearly every aspect of our daily life is controled by unconcious habits that cater to our emotions, certain thoughts, physical stimuli, etc...
Changing a habit requires numerous trial & errors. You must be creative with the Loops & Rewards you give yourself. Pinpoint where the bad habits root from (Trigger,Loop, or Reward).
