Having walked on the Moon, I know something about what we need to explore, really explore, in space.

My first biography written in '73 was not 'Journey To The Moon.' It was 'Return To Earth.' Because for me, that was the more difficult task - disappointment.

I think the American Dream used to be achieving one's goals in your field of choice-and from that all other things would follow. Now, I think the dream has morphed into the pursuit of money: Accumulate enough of it, and the rest will follow. We've become more materialistic. For balance, I think we need to get back to idealism and patriotism, but also be realistic with our monetary goals.
