Desires that stop, desires that don't

Hunger ends. You eat, and the wanting switches off until tomorrow. Thirst ends, cold ends, tiredness ends — the body's real needs come with a built-in stopping point, and you can feel the exact moment they're met. Now think about the other kind: the next rung, the bigger number, the title above the one you just got. Notice that those never click off. You hit the goal and the goal moves. That's not a flaw in you. It's the nature of the want.

Seneca drew this line for a friend who kept chasing more: the desires that come from nature have a limit, but the ones that grow out of false opinion have no place to stop (Letters 16, paraphrase). A natural want is a cup that fills. An opinion-born want is a cup with no bottom, and you can pour your whole working life into it and never hear it ring full.

The practice today is to sort one want into the right bin. Is this hunger, or is it a bottomless cup someone taught you to carry? Feed the first. Set the second down before it drains the shift.
