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

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

We all have two lives. The second begins when we realise we only have one. 

The gift of imperfection - let go of who you think you're supposed to be and embrace who you are.

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

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

The journey of a thousand miles begins with one step. 

Nobody said it’d be easy, they just promised it would be worth it.

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

Success is a journey, not a destination.

Hard work always pays off - it is not a question of if you will get there, but WHEN you will get there

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

It always seems impossible until it's done.

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

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