Perhaps you don’t love your work, especially if you are past your prime and tormented. Perhaps it is like a tense marriage. Still, quitting feels like death or divorce, and before you do it, it is like standing at the edge of a cliff.

You are looking out over a precipice, unsure whether what awaits will bring net pleasure or pain—or, most likely, both. But you know what you have to do. Don’t think, dude. Just jump.
