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. 

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

Everything that happens was once a dream.

Patience is when you’re supposed to get mad, but you choose to understand

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

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

If you fail, next time fail better.

Hard work always pays off - it is not a question of if you will get there, but WHEN you will get there

Hope might be a good breakfast, but it makes a very poor dinner

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

There is great wisdom in being able to realise that you don’t understand something before it goes too far.

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

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

Lose an hour in the morning and you will spend all day looking for it.
