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

It doesn’t matter where you start, it matters how you end

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

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

The greatest mistake we make is living in constant fear that we will make one.

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

Never underestimate the importance of small steps. small steps = big changes. 

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

The greatest enemy to human potential is your comfort zone

Time is your friend, impulse is your enemy.

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

There are no bad mistakes in maths, only discoveries.

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

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

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