There are no bad mistakes in maths, only discoveries.

There is no elevator to success, you have to take the stairs.

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

You can have results or excuses, not both

The greatest enemy to human potential is your comfort zone

Mistakes have the power to turn you into something better than you were before.

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

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

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

It is never too late to become what you might have been

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

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

We learn more from failure than we do from success.

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

Focus on progress, not perfection. Practise a little bit every day - little and often  Slow and steady wins the race.
