Adolescence is that time in your life when you discover your ability to be depressed.

I'm frustrated with Hollywood and television and the movies because they see science fiction as an excuse for eye candy, for lots of great special effects.

The single most important lesson of effective communication is this: Focus on clarity. Concentrate on precisions. Don’t worry about constructing beautiful sentences. Beauty comes from meaning, not language. Accuracy is the most effective style of all.

My approach to 'Star Trek' was, 'I know science fiction, and I know screen writing.' That was very arrogant of me, but you really need to be a little bit arrogant to think that what you have to say is good enough to justify the expense of hundreds of thousands - now millions of dollars - to make an episode of the TV show.

I have memories - but only a fool stores his past in the future.

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.

If you're passing the buck, don't ask for change.
