Don’t compare yourself to others. Compare yourself to the person you were yesterday.

Go as far as you can see, when you get there, you’ll be able to see further

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

Everything you want is on the other side of fear

The easiest person to deceive is yourself.

You can have results or excuses, not both

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

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

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

Time is your friend, impulse is your enemy.

It always seems impossible until it's done.

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. 

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

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

Dreams don't work unless you do.
