So learn to say No—and be rude about it when necessary.  Otherwise you will not have time to carry out your duty, or to do your own work, and certainly no time for love and happiness. The termites will nibble away your life and leave none of it for you. - Robert A. Heinlein quote.

Writing is antisocial.  It's as solitary as masturbation.  Disturb a writer when he is in the throes of creation and he is likely to turn and bit right to the bone...and not even know that he's doing it.  As writers' wives and husbands often learn to their horror. - Robert A. Heinlein quote.

A long and wicked life followed by five minutes of perfect grace gets you into Heaven. An equally long life of decent living and good works followed by one outburst of taking the name of the Lord in vain—then have a heart attack at that moment and be damned for eternity. Is that the system? - Robert A. Heinlein quote.

Stupidity cannot be cured with money, or through education, or by legislation.  Stupidity is not a sin, the victim can't help being stupid.  But stupidity is the only universal capital crime; the sentence is death, there is no appeal, and execution is carried out automatically and without pity. - Robert A. Heinlein quote.

Jealousy is a disease, love is a healthy condition. The immature mind often mistakes one for the other, or assumes that the greater the love, the greater the jealousy—in fact, they're almost incompatible; one emotion hardly leaves room for the other.  Both at once can produce unbearable turmoil. - Robert A. Heinlein quote.

It is a truism that almost any sect, cult, or religion will legislate its creed into law if it acquires the political power to do so, and will follow it by suppressing opposition, subverting all education to seize early the minds of the young, and by killing, locking up, or driving underground all heretics. - Robert A. Heinlein quote.

I began to sense faintly that secrecy is the keystone of all tyranny.  Not force, but secrecy...censorship.  When any government, or any church for that matter, undertakes to say to its subjects, "This you may not read, this you must not see, this you are forbidden to know," the end result is tyranny and oppression, no matter how holy the motives. - Robert A. Heinlein quote.

There is no way that writers can be tamed and rendered civilized.  Or even cured.  In a household with more than one person, of which one is a writer, the only solution known to science is to provide the patient with an isolation room, where he can endure the acute stages in private, and where food can be poked in to him with a stick.  Because, if you disturb the patient at such times, he may break into tears or become violent.  Or he may not hear you at all...and, if you shake him at this stage, he bites. - Robert A. Heinlein quote.
