what helps me is I offload some of the knowledge for others. If
  I find someone who knows A LOT MORE in something than I feel as
  if I ever could, I just imagine them an alternative Timeline
  "me", born of different parents, and I'm handling the situation
  perfectly well from their perspective and it frees me up to work
  on other projects - and keeps me from being envious because,
  well, it's just another 'me' working on it.

  narcissistic? Sure*tongue emoticon
