This weekend I was having a really hard time writing, and feeling overwhelmed by it. I think the solution is to unplug this weekend and hopefully on Friday or Monday if I can get one of those off from the day job. Then I can just write. It often helps to have an uninterrupted stretch of time, especially several days in a row, because then I can build up momentum. It also helps not to have other things tugging at your attention, which I won't quite manage this time, but I'll do my best to ignore things.
I'm about halfway through the draft of The Duke and the Pirate Queen. Sometimes I think it's not bad at all, sometimes I think it's a mess and have no idea what I'm doing.
If someone invented a writer confidence pill, they would make a mint, if only writers had any money to buy the things. (I'm assuming the really, really bad writers wouldn't buy such a pill, because they would already think they're brilliant and don't have to do anything to get better.)
