Another way that overconfidence manifests itself is in how much motivation you decide to muster for a particular goal. In particular, you’ll tend to not use enough motivation hacks. You’ll think, “I already run sometimes without even pushing myself. If I set a schedule to run three times a week, and I tell a friend that I’m doing it, it’ll be easy.” Such optimism is human and must be fought. Set up more motivation hacks than you can ever imagine needing.
