I was supposed to go to Julliard Music school (USA) when I was
  10.5/11. Everybody prompted my mother to get me to get special
  lessons for it and so I did for months. Training for the
  school's entrance thing. After six months of practice geared to
  help my entry, I pulled her aside and asked her if I *had to* go
  to this school. I didn't want to: I could see what my future
  would hold [the negative side anyway]: Repetition, perfection,
  competitions. Performing, Being judged. Levels. Grades.
  Mistakes. Corrections. Travel. I didn't want any of it. It
  seemed dreadful. But without having to launch into any long
  explanation to her, she agreed and without disappointment. I
  never regretted it. He says: "The honest answer to this question
  is: don*t do it. Unless you absolutely have to be a musician
  because it*s the only thing you can do and you can*t stop
  yourself. But if there*s any choice * go and be a doctor or a
  lawyer because being a musician is a nightmare." and that speaks
  to me. "Unless you absolutely HAVE to be a musician because it's
  the only thing you can do and can't stop yourself". That speaks
  volumes. Don't just "try it 'cause you like it". You have to
  have full-on commitment, be willing to do WHATEVER it takes. I
  didn't. I knew it as a kid. Everybody else thought I could and
  should. I knew they were wrong. Thankfully I had a mother who
  listened. His early story is a lot like mine. I didn't HAVE TO
  be a musician. I liked playing music. I enjoy making music. It's
  natural. I love it. It plays in my head 24/7. I hear music
  everywhere. But a career would have killed it. Killed it. I know
  it would have. Even if it didn't and I was wrong, I don't regret
  it. I wasn't committed. I would never become committed. It's
  likely I would've ended up like him. Bitter. Negative. He
  reminds me so much of me it's disturbing. Instead, I'm happy. I
  enjoy playing. I didn't get wrapped up in the System as it is.
  I'm very glad to be outside of it. Very very glad.

  you, I encourage EVERYBODY to follow their dreams. Really. I
  believe it so fully I can't even put words to it. But: be ready.
  Plunge ahead eyes open or shut - it doesn't matter. But you have
  to be committed or trust someone to be committed for you. I
  would've been walking in naked by myself. I had no mentor. == I
  was a kid with grown adults around me going, "I would KILL to
  have your talent!". "You have SO MUCH POTENTIAL, you shouldn't
  waste it". "You don't understand how precious a gift is that you
  have". All these people trying to manipulate me. Grown adults
  being envious... jealous. Piano teachers drooling to be able to
  do what I could do, play how I could play. "You have more
  creativity in your pinky nail than all of my students will have
  in their lives". Fucking shit. That kind of pressure. They had
  no idea how rotten that was to do to a kid. Excuse the language
  but even at 44 yrs old, when I see parents/teachers/adults
  pressuring kids to "be" this or that. engineering their
  existences out of them... and then wonder why they off
  themselves as a teenager and those left behind cry how much
  potential they had.... my rage goes at the parents and teachers
  more than the sympathies. I was _very very_ lucky. Very lucky. I
  got through it intact but I brought a nugget with me through
  time itself - I vowed I'd never forget the undue pressures
  adults put on kids who have talents they didn't even ask for and
  I'd never do the same to anybody. I hope I succeeded. Ugh. Sorry
  for the rant but it's something I'm passionate about. Thanks for
  giving me the space to express myself
