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

In order to become better than anybody else you must first become better than yourself.

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

No matter how bad it gets, you’re still way ahead of those who haven’t even started.

Go as far as you can see, when you get there, you’ll be able to see further

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

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

It is never too late to become what you might have been

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

You'll never change your life until you change something you do daily. The secret to success and change in found in your daily routine.

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

Success can never happen without the journey (struggle).

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

Everything that happens was once a dream.
