What is Best?

Sometime it's so hard to know how to be the best.
I wanna be the best but I couldn't
I thought I am the best but I'm not.
Confident is good, but it kills me sometimes.

People said "try your best" but I will say "I'll be the best"
How to be not so over confident when everything around you is things you don't think it's their best?
maybe i need to respect and appreciate what people's best.

That's something I need to learn from now.
No more over confident and looking down on people.
