“Rule No. 1: Never lose money. Rule No. 2: Never forget rule No. 1.”
This maxim (perhaps of gambling or horse racing origin) is widely attributed to Warren Buffett and, as such, has traditionally been cited in print; notably, it was attributed (perhaps facetiously) to him by Mary Buffett in, The Tao of Warren Buffett. A more uncommon, less well known version, and perhaps one with a more lasting credibility (or certainly with a higher degree of checkability), would be: "The first rule is don't lose, and the second rule is never forget the first rule." This version was noted by Steve Forbes in a friendly meeting in Omaha, in an article published as: Jay-Z, Buffett and Forbes on Success and Giving Back. This article is available on the Forbes website, published on September 23, 2010.
