A job you quit after a month still taught you what you can’t stand. That’s useful data.

A short job is not a wasted month. You found out something hard to learn any other way: which parts of work you can tolerate and which ones grind you down by Wednesday. The noise, the standing, the manager who changes the plan hourly, the absence of anyone to talk to.

Write down three things about that job you could not stand, and two you did not mind. Keep the note somewhere you will find it again. Read it before you say yes to the next place.
