I think I'm the best, of course. How could I not?
You have it or you don't... I think I have it.

Never think you've seen the last of anything.
I think; therefore I am.
What we think, we become.
We are what we think. All that we are arises with our thoughts. With our thoughts, we make our world.
Be realistic, demand the impossible.
