I recently had the occasion to apply George E.P. Box’s famous quote “…all models are wrong, but some are useful.” in a work discussion, and it got me thinking about all those other great and insightful quotes that come in handy (E-mails, presentations, etc.,). So I went on a short search and stumbled on this most excellent list from a stackexchange post. I also stumbled on this list (by following a link from R-bloggers).
