People equate success with youth. And if you haven't had a certain amount of success by a certain time in your life, it's never going to happen. There's a fear about that. So people start lying about their age really young. I've never done that because I think it's so insignificant.

This quote is saying that people often assume that you must achieve success while you are young. This can create fear and pressure to be successful, and some people may try to hide their age in order to appear more successful. The person speaking believes that lying about your age is unnecessary and won’t make a difference.
