I just found out about this book, which is published for free (no less) by Raytheon. It is a compendium of wisdom from the Raytheon CEO. Many of the rules are applicable to just about any life situation.
UPDATE - It has been pointed out to me that Mr. Swanson did not originate these rules...in fact it seems that he has been guilty of plagiarism, in that many of them were lifted from other people's work. What is it with these people in corporations who inflate their resumes or steal other people's work?
UPDATE 2 - Richard Veryard responded in his typically thoughtful way in the Comments section, also pointing to an article by Vannevar Bush. I located the article online here for anybody who wants to study it.
