"Now, isn't imagination a precious thing? It..." - Quote by Mark Twain

“Never mistake motion for progress.”

“Do the thing you fear most and the death of fear is certain.”

“I am the entire human race compacted together. I have found that there is no ingredient of the race which I do not possess in either a small way or a large way.”

“Kids like us don't often have the chance of meeting a great warrior like you. Would you have a little fencing match with me? It would be frightfully decent.”

“There is an astonishing imagination, even in the science of mathematics.”

“Age continually alters the faces of those who think or study, and so their portraits differ from one another and don't even resemble them for very long. I dream so much and live so little that I'm sometimes only three years old. But the next day I'm three hundred, if the dream has been sombre.”

“Every time an artist dies, part of the vision of mankind passes with him.”

“Genius is always sufficiently the enemy of genius by over influence. The literature of every nation bear me witness. The English dramatic poets have Shakspearized now for two hundred years.”

“There are certain kinds of people who write science fiction. I think a lot of us married late. A lot of us are mama's boys. I lived at home until I was 27. But most of the writers I know in any field, especially science fiction, grew up late. They're so interested in doing what they do and in their science, they don't think about other things.”
