The greatest enemy to human potential is your comfort zone

Just stick with it, what seems hard now will one day be your warm up.

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

Success is a journey, not a destination.

I have not failed, I've just found 10,000 ways that won't work.

Dreams don't work unless you do.

Success can never happen without the journey (struggle).

No one starts out on top. You have to work your way up.

You can have results or excuses, not both

Hard work beats talent when talent doesn't work hard.

Time is your friend, impulse is your enemy.

A hero is no braver than an ordinary man, but he is braver five minutes longer.

Everything you want is on the other side of fear

We learn more from failure than we do from success.

Nothing is impossible if you want it badly enough. Impossible = I'm possible.
