I have not failed. I've just found 10,000 ways that won't work.

This statement means that trying something that does not work is not a failure. Instead of seeing it as a failure, it means that a person has discovered one way that does not work out of 10,000 possibilities or ways. We can use this experience to focus on the other 9,999 possibilities. This statement encourages us to keep going even if things don’t work out the first time.
