I didn't care about this sports argument until I saw the things you said. You're so cocky. And I honestly don't mean that in a rude way, but it's the truth. You're not the best. You should never feel that way. There's always room for improvement. You're not the best with that mindset. :)
If you believe you're the best you'll play like it. The best know that they're the best. But ok, I'll start putting myself down. If that makes you feel better?
