I sat there thinking, again, why I felt that I had failed and how could I muster up the energy and enthusiasm to try again. It seemed pointless; I would only fail. Then I saw my daughter, 15 months old, trying to walk.

She stood by the chair and stumbled forward and fell. I felt for her, but she just lifted her head and smiled and tried again and fell once more. Again she smiled, no bruised ego. She just got on and tried once more and took her first step.

A lesson for me could not have been given more plainly. We don't know until we try and if we fail, we just have to try again.
