If you have run your own business and have not had the highs, and the lows, you’re a better man than I Gunga Din. Running an SME is fraught with setbacks hopefully we learn from our mistakes and keep going, the following appealed to me:

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.
