So why are you upset?

I probably sucked more today than anyone in the history of kung fu. In the history of China. In the history of sucking!
And the Five! Man, you should've seen them! They totally hate me. How is Shifu ever going to turn me into the Dragon Warrior?

I mean, I'm not like the Five.
I've got no claws, no wings, no venom.
Maybe I should just quit and go back to making noodles.

Quit, don't quit.
Noodles, don't noodles.
You are too concerned with what was and what will be.
There's a saying: Yesterday is history, tomorrow is a mystery, but today is a gift.
That is why it is called the present.
