Wecome to the club brother!!
Most people on this forum have some sort of project A.D.D......some of us are afflicted way worse.
To complicate things, there are those moments when you realize your first, or second, or third plans for a certain aspect just aren't what you want them to be. The rework, the money, the days off the calender, it wears on you. All in pursuit of perfection, full well knowing perfection is unattainable, it doesn't exist, you press on. Cutting up perfectly good parts fresh out of the box, modifying your plans, telling yourself "what's a couple more days?" Deadlines come and go. Weld shows up in your thread to tell you how many cars he has finished since you started
You _love_ the car but you hate what it has done to your life.....consuming every waking moment. Your mind wanders, you go a little crazy really. You start to think an amphicar would be fun. Cool stuff comes in the shop and you think you would rather have that. You miss the little projects of throwing parts at a late model, compared to the prototype work we do on early stuff, drilling holes in a late model is a cake walk. You need some time off, so you go to a car show or a track event, as if breaking something on the car you have is a vacation.
You are not alone. Just this moring I had two future projects run through my head.....a 58 Edsel with a GT500 powerplant and a chassis to carry it but done up like a bellflower custom, candy, metalflake, lace, etc.....from that it was a 29 roadster with an aluminum flathead, pretty traditional car with two sets of wheels and tires designed to murder the Goodguys autocross with the right driver. That was this moring. I haven't worked on my Mustang in 2 months.......Shop has been busy....life has been busy
I try not to think about my mortality.....everybody dies, I'm going to do something different.
