The impulse behind fantasy I find to be dissatisfaction with literary realism. Realism leaves out so much. - Joanna Russ

If you want to be an assassin, remember that you must decline all challenges. Showing off is not your job.
If you are insulted, smile meekly. Don’t break your cover.
Be afraid. This is information about the world.
You are valuable. Push yourself.
Take the easiest way out whenever possible. Resist curiosity, pride, and the temptation to defy limits. You are not your own woman and must be built to last.
Indulge hatred. Action comes from the heart.
Pray often. How else can you quarrel with God?

Sex doesn't last.

Fantasy is reality...Surely the mode of fantasy (which includes many genres and effects) is the only way in which some realities can be treated.I grew up in United States in the 1950s, in a world in which fantasy was supposed to be the opposite of reality. 'Rational,' 'mature' people were concerned only with a narrowly defined 'reality' and only the 'immature' or the 'neurotic' (all-purpose put-downs) had any truck with fantasy, which was then considered to be wishful thinking, escapism, and other bad things, attractive only to the weak and damaged. Only Communists, feminists, homosexuals and other deviants were unsatisfied with Things As They Were at the time and Heaven help you if you were one of those. I took to fantasy like a duckling to water. Unfortunately for me, there was nobody around then to tell me that fantasy was the most realistic of arts, expressing as it does the contents of the human soul directly.”
