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. 

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

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

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

Everything you want is on the other side of fear

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

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

Don't fear failure, fear being in the same exact same place next year as you are now.

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

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

It is never too late to become what you might have been

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

The greatest enemy to human potential is your comfort zone

The bad news is time flies, the good new is that you're the pilot.

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt.
