80/20 Rule

I'm new to this. I started my first rebuild almost a year ago, and I was very intentionally wanting to spend 20% (or less) effort just to get it back on the road as soon as possible. I foolishly thought it might take a month if I took my time. Then I started thinking about performance, and the whole "well, while the engine is out, I might as well do X and Y and Z." So after consulting the brain trust here, I've learned volumes of how things work in my car and I've slowed my roll. I realize it's not a race to get it done, it's more important to get it done RIGHT. Sometimes I pop the hood and don't even work on it, I just look things over to make sure I'm not forgetting anything.

So after a year of pissing off my HOA with a non-running car in my driveway, I'm thinking I might have the 80/20 deal backwards...80% effort with 20% of the performance potential realized...
