Everything you want is on the other side of fear

Time is your friend, impulse is your enemy.

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. 

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

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

FAIL - First Attempt In Learning

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

MATHS = Mistakes Allow Thinking To Happen

It is never too late to turn an unproductive day into a productive one.

There are no shortcuts to any place worth going.

There are no bad mistakes in maths, only discoveries.

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

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

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