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. 

The journey of a thousand miles begins with one step. 

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

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

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

I can is 100 times more important than IQ.

The temptation to quit will be the greatest when you are about to succeed

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

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

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

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

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

The road to success is like a staircase. If you want to succeed, double your failure rate

Fall down seven times, stand up eight.

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