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

The temptation to quit will be the greatest when you are about to succeed

I have not failed, I've just found 10,000 ways that won't work.

It doesn’t matter where you start, it matters how you end

Failure to prepare = preparing to fail

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

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

Everything you want is on the other side of fear

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

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

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

Success is a journey, not a destination.

Do what you have always done and you will always be what you have always been

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

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