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. 

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

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

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

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.

There are no shortcuts to any place worth going.

Instead of finding reasons why you can't, find reasons why you can.

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

In order to become better than anybody else you must first become better than yourself.

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

If you want to succeed, double your failure rate.

We all make mistakes. What matters is how we choose to move forwards from them.

A hero is no braver than an ordinary man, but he is braver five minutes longer.

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