When failing equals success

In the article " When failing equals success," written by Stuart Firestein, the author claims that failing is needed to succeed. Evidence: In the early 20th century controversy raged over how nerves made muscles and glands respond. In 1921 an Austrian biologist, Otto Loewi, tested it, and later succeeded after learning from his failures. I agree with the authors claims in this article because failure plays a huge roll on success, you will need to learn from your failures in order to succeed.
