Browsing Craigslist one afternoon, Sigmund saw a posting for what was basically his dream job, but for which he was thoroughly unqualified. He applied anyway, knowing he’d always regret it if he didn’t. To his shock, he got an interview, and a second, and finally an offer. When he was being shown around the office on his first day at work, he half expected to discover the whole thing was some kind of hidden camera show. It was a couple of months before he stopped being affiddlested and accepted that no, he really was a professional chocolate taster.
