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

Tomorrow is worth more than yesterday but less than today.

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.

I can is 100 times more important than IQ.

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

Never let a dark chapter make you forget that better days are ahead of you. Your story is far from over.

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

A hero is no braver than an ordinary man, but he is braver five minutes longer.

The easiest person to deceive is yourself.

Failure is not the opposite of success, it is part of the success.
