ETR nailed it. I may be a cranky, eccentric old bugger pottering about in my wherever, but I'm happy there, damn it!
Being organised does help with hobbies, as it does with so much in life. Or as one friend told me, "Life is too short for chess. But that's not the fault of chess"
Hobbies I've had and, well, not forgotten, but not had enough time for:
Running (I trained for marathons but never ran one), chess (I was a competitive player before China), guitar (still need to restring mine) photography (I'm terrible) writing short fiction(terrible), badminton (terrible), and volleyball (terrible with bad knees)
Oh, and teaching ESL/EFL. Yeah, it's my job, but I enjoy it too much to call it work so it must be a hobby.
