I played Keyboard in primary, but eventually gave up (no fun anymore when the teacher keeps nitpicking about the "correct" way to have my hands when playing). Picked up guitar, but stopped when I switched schools. I picked it up again the second year of yet another new school, but abandoned music forever that same year.
If I was going to pick up music again, it would be drums, nothing else. I'm great at keeping a beat, and learning how to keep up an increasingly complex set of beats seems far more interesting than spending 3-4 weeks to master simple songs.
