Heinlein's rules for living:
Taxes are not levied for the benefit of the taxed.
An armed society is a polite society.
A committee is the only known form of life with a hundred bellies and no brain.
Wisdom is not additive; its maximum is that of the wisest man in a given group.
Always store beer in a dark place.
Beware of altruism. It is based on self-deception, the root of all evil.
Do not handicap your children by making their lives easy.
Never attempt to teach a pig to sing. It wastes your time and annoys the pig.
