I took Spanish in high school and I didn't do too well in it. My Spanish teacher told me not to go on with Spanish anymore so I was discouraged a little bit.
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.
