No man ever achieved worthwhile success who did not, at one
time or other, find himself with at least one foot hanging
well over the brink of failure.

Everyone likes success. Failure isn't always a bad thing because you learn from your mistakes and It adds to experience as long as you don't make that same mistake. Failure is important to the experimental process. That means when you fail at something you try to improve and definitely get better results which lead to success.
