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. 

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

You cannot escape the responsibility of tomorrow by evading it today

Success is the sum of small repeated efforts, day in and day out.

Whenever you find yourself doubting how far you can go, just remember how far you have come.

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

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

It is never too late to turn an unproductive day into a productive one.

Everything you want is on the other side of fear

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.

We all have two lives. The second begins when we realise we only have one. 

A book a day keeps the stupidity away.

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

You can be shown the path, but only you can make the first step.

The journey of a thousand miles begins with one step.
