Hey everyone, I [20m] Am recently single and I have no social life anymore. I feel like I'm too young to be either working or hanging out alone every day. Where can I go to meet people to have fun with? I always find myself wanting to develop social skills and make new friends but everywhere I go I usually don't meet anyone. I work with only one person (my boss) everyday, and taking classes seems like a forced way to meet people. Back in high school it seemed so easy to meet people. You'd hear about a party and end up making 5 new friends. Any advice?

Tl;dr: How can I develop a social life?
