Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

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

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

Skills are built not born.

Run in the morning before your body figures out what you're doing

There are no bad mistakes in maths, only discoveries.

The temptation to quit will be the greatest when you are about to succeed

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

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

You cannot escape the responsibility of tomorrow by evading it today

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

You can be shown the path, but only you can make the first step.

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

The easiest person to deceive is yourself.
