Wow chary! How do you fit all that in, even without working a 'regular' job? Sounds like you have loads of fun, though!
I would say that the thing I do the most is go to shows. 'Shows' generally being DIY punk/indie gigs. I've been doing that ever since the age of 15 and it still makes me happy happy happy. It's almost a way of life rather than a hobby, since so many of my friends are in bands and most of what we do revolves around music.
That sounds like my life 15 - 20 years ago! How things have changed for me (but I am a middle-aged lady now

)
1. Playing (mostly Irish trad music) my Celtic harp and fiddle are my main hobbies / activities. I've done a handful of paying gigs as well, but need to get more of those!
I also play with 4 other harpists and we have a little ensemble. My hubby and I play together a bit (we've got a wedding gig coming up in July). We go to a regular open mic night when we can which is run by a friend of ours.
2. I do love walking in the countryside (when it's at a pace I can keep up with).
3. Another interest is in ancient sacred sites (stone circles, holy wells, tombs, dolmens, standing stones, etc.) I've got to get down to chary's neck of the woods as my favorites are down there (bottom of Cornwall) and I have't been for ages!
4. Reading, especially books of alternative healing modalities, self-help, psychology and spiritually related topics.
5. I like to cook and bake, but don't know if I do it often enough or push myself enough with it to call it a hobby.
That's about it. I used to sew, make costumes, paint, draw; I don't do any of that since I've been in the UK, not sure why, just don't enjoy it as much anymore.
