I think, therefore I am.

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

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

Failure to prepare = preparing to fail

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

The easiest person to deceive is yourself.

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

Just stick with it, what seems hard now will one day be your warm up.

You can hire a tutor but you can't hire someone to practice for you.

Everything that happens was once a dream.

Don’t hang your targets after you’re done shooting.

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

There are no bad mistakes in maths, only discoveries.

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

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.
