The journey of a thousand miles begins with one step.

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

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

Dreams don't work unless you do.

Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

Success is a journey, not a destination.

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

The bad news is time flies, the good new is that you're the pilot.

The journey of a thousand miles begins with one step. 

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

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

You can be shown the path, but only you can make the first step.

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

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

If you fail, next time fail better.
