Every time I finish a book, I have a brief, hard emotional low; today was no exception. I mention this not because I'm seeking sympathy but because if it happens to you or someone you love, it's not just you/them, and it's not necessarily due to anything someone should have done differently. I think I'm through it and ready to enjoy my day off tomorrow. I hope so.
I am very good at putting my head down and working. I am not so good at doing things for fun and to reward myself and just to have a break. I default to practicalities, when I'm dealing with myself. This is not a good thing. It is a trait I need to fight. I need to fight it, however, not as A Project, because that defeats the purpose.
So tomorrow I'm not working on the book, but if something occurs to me, I will put it on a notecard and walk away from it. I will think about what I want to do rather than what I need to do or what I want to avoid doing. I think this sounds remarkably like a plan; we'll see if it survives contact with reality.
