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.

Failure is NOT your destiny. Failure is the key to success.

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

Life is full of opportunities. With every opportunity that is missed, another one is born.

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

If you fail, next time fail better.

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

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

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

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

Failure is not the opposite of success, it is part of the success.

The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.

Don’t confuse your path with your destination. Just because its stormy now doesn’t mean you are headed for failure.

Tough times never last, but tough people do.
