Burnout: "Compare how you feel at the end of a productive day vs. the end of a day spent mired in distractions and unfocused activity. Both days make you feel tired. But the quality of �tired� is different. When 5:00 comes, and you can identify solid progress toward your most important goals, you tend to feel satisfied, even energized, although you may also feel tired. But it�s similar to the �tired� you feel at the end of a good workout. And the idea of doing it again feels good. "
