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

No matter how bad it gets, you’re still way ahead of those who haven’t even started.

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

Tough times never last, but tough people do.

Do what you have always done and you will always be what you have always been

There are no bad mistakes in maths, only discoveries.

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

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

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

Hope might be a good breakfast, but it makes a very poor dinner

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

He who has begun his task is half-way done. Have the courage to begin!

Don't fear failure, fear being in the same exact same place next year as you are now.

It always seems impossible until it's done.

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