What’s love got to do with business?

It’s true that every year people buy/listen to millions of love songs and read millions of love stories. (Online, offline… what line?) Maybe it’s just me, but if there’s one thing that people don’t seem to be able to get enough of, it’s love. How is it possible, then, that the vast majority of the great professions, brands etc. (read 99%), which proclaim to be ‘people-centric,’ do not include love (not the romantic kind) in their training curriculum and/or core values?
