Mistakes have the power to turn you into something better than you were before.

Success can never happen without the journey (struggle).

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

Don't fear failure, fear being in the same exact same place next year as you are now.

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

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

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

Start, struggle, fail, fix and learn. Repeat.

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

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

The journey of a thousand miles begins with one step. 

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

Try and do one thing each day that you would really rather not do.
