It took me better than a quarter century to learn, the hard way, that hard work at something you want to be doing is the most fun that you can have out of bed . . . to learn that the smart man finds ways to make everything he does be work; to learn that "leisure" time is truly pleasurable (indeed tolerable) only to the extent that is its subconscious grazing for information with which to infuse newer, better work.

there's nothing in the human heart or mind, no place no matter how twisted or secret, that can't be endured - if you have someone to share it with.

Some guys step on a rake in the dark, and get mad and go punch somebody. Others step on a rake in the dark and fall down laughing at themselves. I know which kind of guy I'd rather be. So do my friends.

And I repeat: if there is anything that can divert the land of my birth from its current stampede into the Stone Age, it is the widespread dissemination of the thoughts and perceptions that Robert Heinlein has been selling as entertainment since 1939.

Shared joy is increased, shared pain is lessened.
