They say a random quote is like reading obituaries from an 18th century newspaper on the other side of the world. The information is worthwhile to someone, but probably not the person actually reading it.
All right, so I made that up, but regardless, meaningful, unique quotes can be difficult to come by, unless you are perusing Food for Thought. The site is billed as "A Collection of Heretical Notions and Wretched Adages compiled by Jack Tourette."
Start off by searching a specific letter of the alphabet, which will turn up tags, or categories, of quotes. Or you can search for specific words to find interesting stuff. It doesn't appear to actually search the quote itself, though. A search for "quote" turns up this tidbit from Nathaniel Hawthorne: "Happiness is a butterfly which when pursued is always just beyond your grasp, but which, if you will sit down quietly may alight upon you." The source, however, uses the word "quoted."
Anyway, the next time you need something profound to say, and you can't bring yourself to using the B.S. Generator over and over in your boring meetings, try Food for Thought instead. I should warn you, though, that there are no quotes about muffins. I checked already.
