I think what Micheal is going through, is the same anxiety I get near the end of every project I`ve ever started. You start to second guess yourself, wondering if you`ve done everything correctly. Even though I`ve literally completed hundreds of projects,(some big, some little)and I`ve been working on cars for over 18 years now. I still go through this at the end of every job. I think it makes me a better mechanic, because I pay closer attention to detail, and I follow the book. I don`t assume that I know it all, and I`m not afraid to ask questions. As for Johnson size, not everyone with a fast car is lacking in that area(at least that`s what I keep telling myself)
