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. 

Procrastination makes easy things hard and hard things harder.

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

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

A book a day keeps the stupidity away.

In order to become better than anybody else you must first become better than yourself.

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

Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

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

It is never too late to become what you might have been

We learn more from failure than we do from success.

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

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

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

No one starts out on top. You have to work your way up.
