It is worth noting that it is important to select short-term rewards that reinforce your identity rather than ones that conflict with it. Buying a new jacket is fine if you’re trying to lose weight or read more books, but it doesn’t work if you’re trying to budget and save money. [...] Similarly, if your reward for exercising is eating a bowl of ice cream, then you’re casting votes for conflicting identities, and it ends up being a wash. Instead, maybe your reward is a massage, which is both a luxury and a vote toward taking care of your body. Now the short-term reward is aligned with your long-term vision of being a healthy person. Eventually, as intrinsic rewards like a better mood, more energy, and reduced stress kick in, you’ll become less concerned with chasing the secondary reward. The identity itself becomes the reinforcer. You do it because it’s who you are and it feels good to be you. The more a habit becomes part of your life, the less you need outside encouragement to follow through. Incentives can start a habit. Identity sustains a habit.
