That's why Keith's voice is so awesome - he genuinely doesn't
  know just how good he is. That's what propels creative ppl to
  get better and better - their standards are so impossibly high
  and they're never good enough - but meanwhile while they climb
  up the mountain of perfection, trying to make reality match the
  image of Perfect they have in their heads, , they never look
  back to realize, "holy crap - I'm higher/better than 99.999% of
  humanity. I can stop climbing now and perform something.. I *am*
  Awesome after all". "
