You *can* have success without failure.

  How?

  Go through all of the failures in your mind and on paper (or
  computer), brainstorm with other people and make plans for all
  failures you can *possibly* think of.

  Pressed for time or impatience, most of us don't have that
  luxury - and no matter how much you plan, there are always
  things you can't plan for. But rather than giving up on
  brainstorming altogether (because we can't think of EVERY
  possibility) - instead DO WHAT YOU CAN and then boldly step
  forward and take that leap of faith... the faith that you've
  crossed every t and dotted every i - and faith in God or
  happenstance or probabilities that you will succeed, not despite
  all of the unknowns, but because you have planned for as many
  unknowns as you could. -Ken
