What have you done in the past? Hobbies which other people can get involved in are a lot more fun for me, and give me some identity. My hobbies: Whitewater kayaking, Rock Climbing (not so much now), Hill Walking, Cycling, Music: Playing guitar, piano etc (better with other people), cooking reading etc. If you REALLY like tech meetups can be fun, but I prefer to do different stuff in free time compared to work.
