I think, therefore I am.

There is no elevator to success, you have to take the stairs.

Success is a journey, not a destination.

The journey of a thousand miles begins with one step. 

The greatest mistake we make is living in constant fear that we will make one.

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. 

Tough times never last, but tough people do.

Skills are built not born.

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

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

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

Everything you want is on the other side of fear

Never underestimate the importance of small steps. small steps = big changes. 

The journey of a thousand miles begins with one step.

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