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

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

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

In order to become better than anybody else you must first become better than yourself.

There are no bad mistakes in maths, only discoveries.

It always seems impossible until it's done.

Life is full of opportunities. With every opportunity that is missed, another one is born.
