Getting Real by 37 Signals

Reading this online book about building successful web-based apps and business philosophies, and already in the first chapter I'm totally inspired. I guess that's the point of an introduction paragraph, huh.

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. This requires not that the writer make all sentences short or avoid all detail and treat subjects only in outline, but that every word tell.
