But also keep a balance and do things you can't do when you are in your 30s. Get physically active in some fun sports, learn how to compete and make friends. Date, a lot, and learn how to have conversations, flirt, and just hang out.
Make mistakes, they are cheaper to correct at your age.
The best thing, as a young person that likes to program, is that you can feasibly code and travel around. So do that. If you are intimidated, start small and just drive to different cafes in your city, or go to different cities. Then find a way to move to another city, even for a few weeks. Tourism is boring, but living other places is awesome. Then think about going to a different country, see the world, but also develop yourself professionally.
Ignore those that tell you to dope up and tune out, that's an absolutely shitty way to spend your young years.
