Of course, why didn't I think of it? To change my bad habits, all I need to do is will it! Truly insightful.
But can I will myself to lie still in bed for two minutes? Much more likely. And, having succeeded and begun the building of a habit, can I lie still for 2.2 minutes the next night? Yes, I probably can.
I thought the point was to rethink how and where we apply willpower and set ourselves up to succeed more often by moving the "succeeding" bar within the realm of our current willpower, rather than holding some standard of "success" that our willpower can never meet.
