Potential…
  Consult not your fears but your hopes and your dreams.
Think not about your frustrations, but about your unfulfilled potential.
Concern yourself not with what you tried and failed in,
but with what it is still possible
for you to do.
Pope John XXIII

Keep on going,
and the chances are that you will stumble on something,
perhaps when you are least expecting it.
I never heard of anyone ever stumbling on something sitting down.
