Any advice for making the most out of my last few days of high school?

I want to end high school on a positive note.

Is there anything you regret not doing before your last day of high school?

what are some advice or tips you have for me before I leave high school forever?

Should I get people’s numbers even if I didnt really talk to them in high school?

My last day of high school is next Wednesday. I’ll have finals all day as well as finals all day on Tuesday.
