The secret of the universe is this: The universe doesn't care. That part of the job is yours.

Morality—like velocity—is relative. The determination of it depends on what the objects around you are doing. All one can do is measure one's position in relation to them; never can one measure one's velocity or morality in terms of absolutes.

Life is hard. Then you die. Then they throw dirt in your face. Then the worms eat you. Be grateful it happens in that order.

A work of art is an act of love. Critics are crab lice.

Doesn't anybody ever want to talk about anything else besides 'Star Trek?' There were 79 episodes of the series; there were 55 different writers. I was only one of them.

Theres two tiers of science fiction: the McDonalds sci-fi like Star Trek, where they have an adventure and solve it before the last commercial, and there are books that once youve read, you never look at the world the same way again.

Notice how every science fiction movie or television show starts with a shot of the location where the story is about to occur. Movies that take place in outer space always start with a shot of stars and a starship. Movies that take place on another world always start with a shot of that planet. This is to let you know where you are. Novels and stories start the same way. You have to give the reader a sense of where he is and what's happening as quickly as possible. You don't want to start the story by confusing the reader.
