The idea is to shift your mindset about exercise from "I should exercise" or "I have to exercise" to "I want to exercise". The author identifies four ingredients for intrinsic motivation: vision, mastery, flow and energy.
Vision is about imagining yourself as the person you want to be, whether that is an exerciser, or a healthy eater or whatever it is you want to change about yourself. As you know, you are what you think, so if you start thinking of yourself as the person you want to be NOW (even if you don't feel like it!) eventually you will become that person!
