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

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

Knowledge is of no value unless you put it into practice.

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

The journey of a thousand miles begins with one step. 

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

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.

Time is your friend, impulse is your enemy.

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

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

Hard work - a two way street where you get exactly what you put in.

It always seems impossible until it's done.

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

You cannot start the next chapter of your life if you keep re-reading the last one.
