How to make a cup of tea (not actually about making tea)

Many, many years ago (sigh) I did a course in Film and Video production run by the local government here in Ireland. It was only ever run once, but it was actually a great course, and I probably owe my entire career to that course. I learned so much from that and much of the experience still serves me today. But there was one class that I always remembered more than any other, and it’s an interesting story, and I wanted to share it, because I think there’s a valuable lesson in it for everyone.
