'think of the future as an open question'

From Scientific American:

[Psychologist Ibrahim Senay of the University of Illinois at Urbana-Champaign] measured the volunteers' intentions to start and stick to a fitness regimen. And in this real-world scenario, he got the same basic result: those primed with the interrogative phrase "Will I?" expressed a much greater commitment to exercise regularly than did those primed with the declarative phrase "I will."

...those with questioning minds were more intrinsically motivated to change. They were looking for a positive inspiration from within, rather than attempting to hold themselves to a rigid standard. Those asserting will lacked this internal inspiration, which explains in part their weak commitment to future change.
