“But sometimes you simply can't make yourself feel like acting. And in those situations, motivational advice risks making things worse, by surreptitiously strengthening your belief that you need to feel motivated before you act.

The subtext is that if you can't make yourself feel excited and pleased about getting down to work, then you can't get down to work.”
