Life is a breadth-first search.
Meet lots of people, and get to know them a little bit. Before you get to know them too well, get to know some other people too.
Try new experiences, learn new things. Some things you won’t enjoy, some things you won’t be good at. If things don’t work out and you cut it off early, all’s well because you’re actively exploring other options.
Resist the urge to commit deep to the first thing that seems good. You won’t have the calm confidence that comes with knowing there’s a lot in the world to like.
