Success can never happen without the journey (struggle).

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

Your attitude is everything. Pick a good one.

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

There are no bad mistakes in maths, only discoveries.

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

Don’t be afraid to work hard and find out how good you can really be.

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

Your limitation - its only your imagination.

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

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

Don’t practice until you get it right, practice until you can’t get it wrong.

No one starts out on top. You have to work your way up.
