This is a great analogy. I have encountered many Museum keeps in my life. But i have always known that our cases are different and so if anyone tells me because he or she didn't succeed and so i wont. I just smile and go on to try.

To succeed, you need to take action. If you failed at first attempt, try again, and again and again. You will succeed at last.
