For a concrete example: in his book "On writing" Stephen King details his life up until the point he hit it big with "Carrie".

Stephen King had his first book Carrie rejected 30 times.
The author of Dr Seuss had his first book rejected by 27 different publishers.
Walt Disney was fired from one of his first animation jobs.
