What hobbies have you abandoned, and why?
Some years ago, I picked up electric guitar, and then dropped it after a year. I think it would just be too much time investment to get to a point where I could perform, and I don’t even like performing. What I really wanted out of it was the ability to recognize and transcribe chords, and I felt frustrated how difficult it continued to be.
Another hobby I used to have was puzzle solving. Like the kind of problems a math teacher might provide “for fun”. Here I just found other hobbies that were similar but felt more fulfilling. Like blogging, or origami.
