I regret not seeking internal transfer within my last employer. I "followed the flow" there for 8 years. Couple years ago I got less happy with project and passively talked with manager about "maybe switching projects in future" — yet stayed on out of laziness and liking the team. The point of no return was when manager/team started being unsatisfied with my performance too.
In retrospect, me unhappy + them unhappy = time to actively seek moving (which they'd still support back then); I stayed into a spiral of feedback => motivation => productivity => ... eventually I was laid off.
I can't know how moving would have worked out but I regret not trying.
[OT: and other passivity, not taking feedback seriously enough, sticking to WFH despite evidence it was challenging for me.]
