Failure is an enigma. You worry about it, and it teaches you something.

The failure of the system to deal quickly was attributable to Nixon's lying, stonewalling and refusal to come clean. So it took 26 months for the final truth to be known.

Nixon's grand mistake was his failure to understand that Americans are forgiving, and if he had admitted error early and apologized to the country, he would have escaped.

I failed the LSAT. Basically, if I had not failed, I'd have been a lawyer and there would be no Spanx. I think failure is nothing more than life's way of nudging you that you are off course. My attitude to failure is not attached to outcome, but in not trying. It is liberating.

Even when you have doubts, take that step. Take chances. Mistakes are never a failure - they can be turned into wisdom.
