“The ultimate form of intrinsic motivation is when a habit becomes part of your identity.  It’s one thing to say I’m the type of person who wants this.  It’s something very different to say I’m the type of person who is this.  The more pride you have in a particular aspect of your identity, the more motivated you will be to maintain the habits associated with it.  If you’re proud of how your hair looks, you’ll develop all sorts of habits to care for and maintain it.  If you’re proud of the size of your biceps, you’ll make sure you never skip an upper-body workout.  If you’re proud of the scarves you knit, you’ll be more likely to spend hours knitting each week.  Once your pride gets involved, you’ll fight tooth and nail to maintain your habits.” ~ James Clear, Atomic Habits
