The journey of a thousand miles begins with one step. 

There are no shortcuts to any place worth going.

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

It is never too late to turn an unproductive day into a productive one.

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

You can have results or excuses, not both

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

The easiest person to deceive is yourself.

I have not failed, I've just found 10,000 ways that won't work.

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

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

You cannot escape the responsibility of tomorrow by evading it today

The master has failed more times than the beginner has even tried

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

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