I woke up at 5.30 this morning, writing in my head. This happens sometimes when I have had an idea the day before that I'm about to work on. In some ways it's good, in others pretty dire. I'm not particularly good on only five hours asleep, and there's no way I can drop off again. On the other hand, it's great to get an early start and not have to carry on working long into the evening if I want to get something finished.
The reason for it today, I think, was because of something that happened yesterday. I didn't have any commissioned work, so I wrote an article for a customer's public request at Constant Content. The pay offered was pretty good so I knew the competition would be hot. Anyway, I got it written and submitted, and it was snapped up straight away. That was the first good news, and then I got a message from the customer asking for more in the same vein. By the time I went to bed I had the idea for the next one going round and round in my head.
This also is not too uncommon, and my strategy for pushing the thoughts away so I can sleep is alwasy to read a book that I'm enjoying for a while before I turn out the light.
