Gabrielle Oettingen would disagree: "During the course of four experiments, Kappes and Oettingen demonstrated that conjuring positive fantasies of success drains the energy out of ambition. When we imagine having reached what we want, our brains fall for the trick. Instead of mustering more energy to get "there," we inadvertently trigger a relaxation response that mimics how we would feel if we'd actually reached the goal.
