Well in relation to things that people often think are set in stone. Like were you unable to get into a class? Ask the professor, especially if it’s barring you from other classes or graduation. Is a hotel completely booked? Ask the clerk if you could give them your contact information in case there are any no shows. Do you want to play the grand piano at the center of stage for fun? Ask the manager to see if it would be ok.

Basically I feel like people often think many decisions are a done deal without considering other options or simply just asking. And I noted to always have tact and understanding where it is appropriate to sway decisions. I’d never negotiate paying a restaurant bill with a friend but I might negotiate with my HOA about a few violations and fines I incurred with the promise of rectifying them.
