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. 

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

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

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.

Never let a dark chapter make you forget that better days are ahead of you. Your story is far from over.

Your limitation - its only your imagination.

Instead of finding reasons why you can't, find reasons why you can.

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

The master has failed more times than the beginner has even tried

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

You cannot start the next chapter of your life if you keep re-reading the last one.

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

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

You can hire a tutor but you can't hire someone to practice for you.

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