“These virtues are formed in man by his doing the actions.” –
“You are what you do repeatedly. So your excellence isn’t an act, it’s a habit.” – Will Durant paraphrasing Aristotle.
Charles Duhigg’s book The Power of Habit breaks habits into three parts: the trigger, action, and reward. In order to create habits (and repeatedly complete the actions we want to achieve our goals), we need to establish triggers and rewards.
