The easiest person to deceive is yourself.

Instead of finding reasons why you can't, find reasons why you can.

You cannot start the next chapter of your life if you keep re-reading the last one.

If you want to succeed, double your failure rate.

Success is a journey, not a destination.

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

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

Everything you want is on the other side of fear

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

It always seems impossible until it's done.

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

There are no bad mistakes in maths, only discoveries.

Don’t hang your targets after you’re done shooting.

Time is your friend, impulse is your enemy.

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