I’ve always been fascinated by people who are passionately obsessed with what they do, no matter what it is. For these individuals, the pursuit of excellence is highly addictive, they are quality-junkies with an insane attention for details. Typically, they have little interest in entertainment and live in a symbiosis with their obsession; others often admire them but tend to avoid inviting them to parties. Yesterday I went to Ten Katemarkt, a neighbourhood market in the West of Amsterdam, for my grocery shopping. Some veggies and a cone of fries was all I was after, in this unexpectedly sunny Dutch afternoon, but I ended up making an interesting encounter instead – the path to serendipity is unpredictable by definition.
