I used to play the flute like 8 years ago, I didn't practice that summer and I was really bad when I came back, I used to be the best (or one of the best) in my flute section, and was chosen for a flute solo which I still have the tape for somewhere around here. Only until recently did I miss playing the flute (I had a vivid dream about playing the flute just recently), but I decided I probably still wouldn't be willing to learn (I think I relied to much on the teacher to lead me through it, and I would never try to practice at home, but I was very good at doing and remembering everything he ever said to me).
When I was 13 or 14 I started teaching myself to sing, I improved fast at first, then I exponentially slowed down in improvement, I thought I was really good at some points, because I was so proud that my voice actually sounded reasonably good to listen to and not really bad like it used to. But I got pretty much no complements from my chorus teacher or parents (who I sang loudly upstairs when they were home almost everyday for months) I tried out for all county chorus and failed to get it, and quit a year after beginning.
I tried to learn the guitar last year and about a month or so ago I tried picking it back up, could barely have the patience to try and learn the notes, and there were the chords which looked way to confusing for me.
