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

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

If you fail, next time fail better.

Pure mathematics is in its way, the poetry of logical ideas.

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

Failure to prepare = preparing to fail

Never underestimate the importance of small steps. small steps = big changes. 

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

It always seems impossible until it's done.

Shoot for the moon and even if you miss you’ll land among the stars/

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

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

He who has begun his task is half-way done. Have the courage to begin!

Don’t practice until you get it right, practice until you can’t get it wrong.

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