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

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

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

"I" not them. Be the best version of you.

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

Fall down seven times, stand up eight.

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

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

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. 

Success is not final, failure is not fatal.  It is the courage to continue that counts.

Time is your friend, impulse is your enemy.

Run in the morning before your body figures out what you're doing

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

There are no bad mistakes in maths, only discoveries.

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