Anything we need to know, we can learn it from a book. Reading, careful study, a little practice, and we’re throwing knives expertly, overhauling engines, speaking Esperanto like natives.

Never stop feeling and seeing and being excited with great things like air and engines and sounds of sunlight within you.

Do you ever have the feeling you're a tourist on earth?

Get this in mind early: We never grow up.

Every word that judges value is circular. 'Good' is 'right' is 'proper' is 'just' is 'good'. But check the examples, and they're not circular at all: Every one says 'makes me happy'.

Good and evil are not what our parents told us, not what our church tells us, or our country, not what anybody else tells us! All of us decide good and evil for ourselves, automatically, by choosing what we want to do!

Mortalhood is a fine state to visit, but you'd better not call it home.
