I'd have to find the book. But there was research that showed that long-term motivating factors like being healthy, weight loss etc. were not as effective as short-term motivating factors like "I like how I feel after I run/workout/..." or It is beautiful to get outside, etc. Basically, focusing on what is good about it now rather than what will be good later is better at building the habit.
