Vigorous writing is concise. A sentence should contain no unnecessary words, a paragraph no unnecessary sentences, for the same reason that a drawing should have no unnecessary lines and a machine no unnecessary parts. William Strunk, Jr.
What I have in advance are people I want to write about and a problem or problems that I see those people encountering and that I want to explore - it all proceeds sentence by sentence, paragraph by paragraph, and scene by scene. Chaim Potok
When I die there may be a paragraph or two in the newspapers. My name will linger in the British Museum Reading Room catalogue for a space at the head of a long list of books for which no one will ever ask. C. S. Forester
When people start writing there is this idea that you have to get everything right first time, every sentence has to be perfect, every paragraph has to be perfect, every chapter has to be perfect, but what you're doing is not any kind of public show, until you're ready for it. Irvine Welsh
