Failure is not the opposite of success, it is part of the success.

The greatest glory in loving lies not in never falling, but in rising every time we fall.

Success is a journey, not a destination.

Don’t be afraid to work hard and find out how good you can really be.

If you fail, next time fail better.

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

Don’t practice until you get it right, practice until you can’t get it wrong.

Whenever you find yourself doubting how far you can go, just remember how far you have come.

It always seems impossible until it's done.

I think, therefore I am.

Time is your friend, impulse is your enemy.

The bad news is time flies, the good new is that you're the pilot.

There is no elevator to success, you have to take the stairs.

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do
