I don’t enjoy distance running but I still push myself to do it. Fitness reasons and it helps vent some frustration after a bad day.

Writing short stories. Reading a short story by Clarke as a kid is what set me towards science and tech in the first place. I don’t like showing them to people I know and usually just prefer to put them up somewhere online completely anonymously.

Fishing’s great, if you can find somewhere to do it.

Day-sailing is the best. A sailing class and small dinghy isn’t that much iirc, but if you can get your hands on a larger vessel there’s nothing better than the feeling of being on open water. If I couldn’t do tech or anything aerospace I’d 100% be in a maritime profession.
