Well, I find this rather invigorating, because I have someone in mind. But it also brings me back to the fact that I really do need to sit down and make a map for my books so that I've got the road laid out, though not yet paved. I really do need to do that. My problem may be the same as yours if you're struggling to finish a writing project--time.
Time used to snail by, but now that I'm nearly ancient (according to my teenager), it moves like a bullet train. I know that one doesn't find time, but makes time. If I want to get these books done, I need to make time. And I feel like I need to make a huge block of time. And huge blocks of time do not just lie around waiting to be picked up and used at my house. I need a weekend retreat. And I'm going to plan one. Soon. I promise. I'll get back to you on it.
