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.

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

Don’t be afraid to work hard and find out how good you can really be.

We learn more from failure than we do from success.

No matter how bad it gets, you’re still way ahead of those who haven’t even started.

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

There are no bad mistakes in maths, only discoveries.

Hard work beats talent when talent doesn't work hard.

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

Your attitude is everything. Pick a good one.

Time is your friend, impulse is your enemy.

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

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

Procrastination makes easy things hard and hard things harder.
