i often thought Lazarus Long was another one of Robert Heinlein's 'alter egos'...here are some quotes from my favorite part of 'Time Enough For Love' - the Notebooks of Lazarus Long...

Money is a powerful aphrodisiac. But flowers work almost as well.

Everything in excess! To enjoy the flavor of life, take big bites. Moderation is for monks.

Little girls, like butterflies, need no excuse.

You can have peace. Or you can have freedom. Don’t ever count on having both at once.

Place your clothes and weapons where you can find them in the dark.

An elephant: A mouse built to government specifications.

Courage is the compliment of fear. A man who is fearless cannot be courageous. (He is also a fool.)

A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects.

anyway i think all of his characters are fascinating men, no doubt.
