This entire paragraph is the best way I've heard this explained. Ever. I am the same way when I work on someone elses car. Get it done ASAP. On my stuff... not so much. I have 3 Mustang projects, and a Lincoln project. None of which are done. I keep my daily driver on the road when it needs work, but I'm in no hurry to finish the toys. As much as I'd like to enjoy them. I think as much as I enjoy it, it also frustrates me. But that's the nature of it. I've replaced so much sheetmetal on my '88 Mustang that I can't bring myself to do anything on that car halfway.. so it sits until I can do it justice. And you're right about starting and not finishing models... it does come with some level of satisfaction for sure.
1. Taco Bell. What can I say, I'm cheap and I like mexican food. 2. Freddie's (smash seared hamburgers and frozen custard... good stuff. 3. Roy Rogers... well, the one around here didn't want to change their menu when the Roy Rogers franchise changed hands, and so they separated and became Roney's, and serve the same menu when they were a Roy Rogers. That Double R burger... mmm mmmmmm
