What are some extreemly random but realistic things to do be fore im 20!?

Live off the wild for a couple days. Go on a road trip with friends. Turn $100 into $1000. Pull a fire alarm. Anything else you want! I suggest not to build a very large list right off the bat, instead create something that is good to start you off, and then add things as you go. While just sitting around you'll think of really good ones!
