"We need to teach a highly educated person that it is not a disgrace to fail, and that he must analyse every failure to find its cause. He must learn how to fail intelligently, for failing is one of the greatest arts of the world."

"Virtually nothing comes out right the first time. Failures, repeated failures, are finger posts on the road to achievement. The only time you don't want to fail is the last time you try something' One fails forward toward success."
