Don’t be afraid to work hard and find out how good you can really be.

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

The power of reflection is the most powerful skill you’ll learn.

There are no shortcuts to any place worth going.

You'll never change your life until you change something you do daily. The secret to success and change in found in your daily routine.

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

Start, struggle, fail, fix and learn. Repeat.

Skills are built not born.

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. 

It always seems impossible until it's done.

Life is full of opportunities. With every opportunity that is missed, another one is born.

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

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

You cannot escape the responsibility of tomorrow by evading it today

Tough times never last, but tough people do.
