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

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

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

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

Life is full of opportunities. With every opportunity that is missed, another one is born.

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

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

Skills are built not born.

Don't fear failure, fear being in the same exact same place next year as you are now.
