This is so my thing. For me, it seems pretty fun to do very different things on my spare time. Everything but not too much of anything. I have no particular hobby that is very "my" thing and I think that's a shame. I have always liked to try new things to do on my spare time and it has been a great time learning new stuff, but I have always stopped when I learned the subject. Since I have no dream of becoming someone big in a particular sport, art or similar, I have always felt finished with different hobbies when I become good at them, or as long as I think it's fun to keep going. Perhaps it's simply as that I just haven't found my style jet.
