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

Practice like you’ve never won. Perform like you’ve never lost.

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

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

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

Success is a journey, not a destination.

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

You can have results or excuses, not both

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

Whenever you find yourself doubting how far you can go, just remember how far you have come.
