If you have other things in your life-family, friends, good productive day work-these can interact with your writing and the sum will be all the richer.
David BrinFor all its beauty, honesty, and effectiveness at improving the human condition, science demands a terrible price - that we accept what experiments tell us about the universe, whether we like it or not. It's about consensus and teamwork and respectful critical argument, working with, and through, natural law. It requires that we utter, frequently, those hateful words - 'I might be wrong.'
David Brin
