According to Elihu Root, "Men do not fail; they give up trying." Author and philosopher Grenville Kleiser had another viewpoint: "The most successful people learn from their failures and use them as stepping stones to success." Success is built on failure. When the day's or week's calls are done, review your misses as well as your hits. Analyze what went wrong and what went right. If you're not failing often enough, then you're failing to try as frequently as you should.
