My success is due more to my ability to work continuously on one thing without stopping than to any other single quality.

The first requisite for success is to develop the ability to focus.

The first requisite of success is the ability to apply your physical and mental energies to one problem without growing weary.

There is far more opportunity than there is ability.

All kids draw and write poetry and everything, and some of us last until we're about eighteen, but most drop off at about twelve when some guy comes up and says, "You're no good." That's all we get told all our lives. "You haven't got the ability. You're a cobbler." It happened to all of us, but if somebody had told me all my life, "Yeah, you're a great artist," I would have been a more secure person.

In my travels all over the world, I have come to realize that what distinguishes one child from another is not ability, but access. Access to education, access to opportunity, access to love.
