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

Tough times never last, but tough people do.

The road to success is like a staircase. If you want to succeed, double your failure rate

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

The master has failed more times than the beginner has even tried

There are no bad mistakes in maths, only discoveries.

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

Success is a journey, not a destination.

Don't expect to be good at maths or understand things straight away. Be patient and persistent. Rome wasn't built in a day, but they worked on it every single day. 

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

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

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

Don’t practice until you get it right, practice until you can’t get it wrong.

Failure is not the opposite of success, it is part of the success.

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