“There are three levels of change: outcome change, process change, and identity change. The most effective way to change your habits is to focus not on what you want to achieve, but on who you wish to become. Your identity emerges out of your habits. Every action is a vote for the type of person you wish to become. Becoming the best version of yourself requires you to continuously edit your beliefs, and to upgrade and expand your identity. The real reason habits matter is not because they can get you better results (although they can do that), but because they can change your beliefs about yourself.”
