The commercial side

I think the gap between this post and the previous one couldn't have been bigger; the despair and starkness of the WWI trenches compared to the story of commercialization that I'm going to tell below. But hey, sometimes my life is just one big potpourri of unconnected things.
Being a project manager at an educational publisher means you have to know a lot about one very particular thing (your subject, in my case biology) and not so much about lots of other things. These include people management, design, finance, marketing, sales, editing, IT, and which business meeting point has the best dinner possibilities combined with the shortest walk back to the train station. We have specialised departments for each of the things mentioned above, with people who have actually studied in their subject, same way as I have studied biology. But they, lucky them, do not really have to know that much about my field to still be able to do their work on my books properly (although our editor now knows more about protein synthesis than she'd ever care to). I, on the other hand, am constantly learning about their specialities.
One of my least developed areas, I and anyone who knows me would say, is commerce. When I call something 'commercial', it's not a positive thing. I never listen to commercial radio stations, for example, or watch the commercial channels on TV. I don't know that I ever owned a piece of clothing that had it's brand displayed for all the world to see. So doing the commercial things that come with the job can sometimes be a bit difficult.
Yesterday was a case in point. We were at a biology convention (the biggest biology convention of the Netherlands) and not only did I have to man our stand (which means talking to the 650+ teachers who attended the convention, answering their questions, handing out free goodies, and on occasion try to get them to buy our stuff), I also had to give a workshop. To be honest, it was only a small part of a bigger workshop, and my part wasn't really that important, and if I hadn't turned up none of the 35 people in the workshop would have noticed. But still, for me it was quite a big thing, because talking in front of a room full of people is not my favourite thing to do.
Thankfully, it all went well. It went better than well, because everybody listened and participated in the short assignment I'd thought up for them, and when we went through the answers they even forgave me for not knowing exactly why something was the right answer at some points (it was about linking words in educational texts, not exactly my area of expertise). I was dead tired and had a pounding headache, but nobody else seems to have noticed that, which was good. My publisher did the other 80% of the workshop and she made the good points and gave the right answers to the questions, to which I added some small bits of info when I thought she was being a bit too brief.
And then we went back to manning the stand and talking to people in friendly manners. I have never had one of those trainings in which you learn to find out whether someone will actually buy your stuff at some point, and how to ditch them as quickly as possible when you know they won't, so some of my conversations may have been pretty useless in a commercial sense, but I had fun and being nice to people is something I like to do. But still, after spending 12 hours anticipating other people's needs, questions and wishes, I'm going to be the most self absorbed person ever for the next 24.
Anyway, it's nice to know I'm slowly mastering yet another part of the jigsaw puzzle that is professional life.
