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

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

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

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

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

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

Skills are built not born.

If you want to succeed, double your failure rate.

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.

If you can understand just one thing thoroughly, then you will understand everything.

The greatest enemy to human potential is your comfort zone

The greatest glory in loving lies not in never falling, but in rising every time we fall.

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

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