Eulogies:Tips and Ideas

Anyone know of any good quote sites that might be useful or a jumping off point for eulogy writing?

That one is by Margaret Meade and it was my mom's favorite. I know there are a few sites out there. http://www.brainyquote.com http://www.great-quotes.com/ http://www.wisdomquotes.com/ http://en.thinkexist.com/
