Some hobbies that might work are astronomy, photography, gardening, hiking, ham radio, home machining or woodworking. All of those are typically slow paced, non-competitive, and do not typically require a natural skill or gift unlike musical instruments or writing. Hope that helps.
Yes. Hiking is something we're starting to get back into now that it's not freezing cold all the time, and I plan on doing some home wood- or metalworking once we have a shed built in a couple weeks.
I'm also starting to get into Warhammer, God help me.
