Happy, Smart, and Useful
Do check out Derek Sivers’ post at sivers.org/hsu. I didn’t realize Sivers already has a Venn chart (when I clicked on the link), but I saw his chart only after I’ve created mine. Which goes to say this article or chapter in his book, Hell Yeah or No, is the perfect recipe for a Venn chart (that’s the first thing that pops in my head as I visualize what I was reading)! The book is a good read.
