"I'm extremely sensitive as to whether the work I'm doing is actually accomplishing anything. And the feeling I get when I'm working futilely feels a lot like burnout, discouragement, frustration, and so on. I've felt this sensation often enough to know that it doesn't mean I need to take two weeks off and then come back and do the same damn useless job. Nor does it mean I need to collapse into a sobbing heap of self-pity. None of those do any good. It ususally just means I need to change my approach so that I accomplish something in the real physical world.
Useful work and tangible accomplishments make burnout go away quickly."
