Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

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

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

You can have results or excuses, not both

A book a day keeps the stupidity away.

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.

Skills are built not born.

You cannot escape the responsibility of tomorrow by evading it today

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. 

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

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

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

Lose an hour in the morning and you will spend all day looking for it.

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

Your limitation - its only your imagination.
