I go for walks. I'm currently in college and live right next to campus. Going for walks during the day (you can listen to music too, if you don't want people to talk to you, that is what I do) allows me to see a lot of people that are engaged in their own thing. I see people walking to class, people playing tennis, volleyball, soccer, and everything on the rec fields, people sitting and reading, people talking, I see people living in the way that I want to live. And over time it helps me to do those same things.
