Oh, yeah, another sound reason for keeping a diary is this one:
Two years ago I was invited to attend a fair organised by a guild of actors, poets and playwrights. The organiser was looking to utilise the rooms in this function hall that wouldn't be needed for readings and acts and seminar, and my name was one that he happened to be given. I wasn't very optimistic because most of the attendees would be in-house, with only a limited foot-fall from the public. It was a two-day event as well, which doubled the costs, but I accepted the invite anyway.
Sure enough, virtually the only viewers consisted of these performing arts folks, so I was expecting low sales. Boy, was I wrong! The organiser bought three pens, his assistant bought two, and others in the guild between them bought four more. Now, these pens were in the £25.00 range so you can see I'm talking useful dosh here. I left for home that evening pleased that I'd had a very good day, but not holding out much hope for tomorrow, seeing as how the same people would be attending.
When I got there next morning the organiser was awaiting my arrival. He wanted another SIX PENS! (Yes, obviously I gave him a very good discount, which is another thing to consider doing in order to cement good customer relations.) See, when he got home and showed everyone his pens they all wanted one, and he became the family buyer, so to speak. And so it was with several of the other attendees. They too came back looking for more, and I was only too happy to oblige.
The point of all this to underline the value of keeping a record. All the facts quoted here I got from my diary after putting up the last post. One final point: You should ALWAYS make a special note where someone buys more than one pen - that person may buy a dozen but is only ONE customer. So, instead of being led astray in a couple of years time and seeing how much dosh you made at so and so event, your note will be there to remind you that most of it came from a single buyer, and that you are unlikely to repeat that success!
