Your turn will come

"Whenever you make a mistake or get knocked down by life,
don't look back at it too long. Mistakes are life's way of
teaching you. Your capacity for occasional blunders is
inseparable from your capacity to reach your goals. No one
wins them all, and your failures, when they happen, are just
part of your growth. Shake off your blunders. How will you
know your limits without an occasional failure? Never quit.
Your turn will come."
