By the time that book So You Want to Be President? came along, we had already had enough presidents that had shown us that presidents are human beings.

I used to teach on a college level, and I've taught in schools where kids just wanted to be artists, and I used to be furious with them if they didn't read, because they just seemed so - their education seemed so thin if all they could do was pick up a paint-loaded brush and fling it at a canvas.
