".....it doesn't matter how many times you fail. It doesn't matter how many
times you almost get it right. No one is going to know or care about your
failures, and either should you. All you have to do is learn from them and
those around you because...All that matters in business is that you get it
right once. Then everyone can tell you how lucky you are."

there, you need to be in a different band. And I think that works for
almost everything that's out there as well." Pat Metheny
