You should be smart enough to know that you don't know everything. But you have to believe in yourself. I certainly do.
You know a lot, but you don't know everything.
As a kid when I was growing up, as any kid, you think you know every thing and I was no different to that.
You never know what's going on in someone's life. You never know what's really going on behind what they present.
When you're very young and you learn something - a fact, a piece of information, whatever - it doesn't connect to anything.
