I build for my own enjoyment, and because I love cars, I dont build to impress anyone, I dont build for contest. I dont sweat the small stuff most of the time, every build is different, some builds I want to do the best I can, some , I tell myself its going to be collecting dust on the shelf, so its not a big deal.
At the same, I do want to get better , sharpen my skills, become a better builder, but I am not going to take the fun out of it, once the fun is gone, its no longer a hobby.
