There are no bad mistakes in maths, only discoveries.

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

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

We learn more from failure than we do from success.

Knowledge is of no value unless you put it into practice.

If you can understand just one thing thoroughly, then you will understand everything.

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

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.

It is never too late to turn an unproductive day into a productive one.

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.

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

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

Procrastination makes easy things hard and hard things harder.

A book a day keeps the stupidity away.
