What are you building? A tree house? If you make significant changes to your house a nosy neighbor might dob you in. Make sure you wear safety glasses. Look what happened to the Australian golfer, Greg Norman. He was using a chain saw doing something on his property which I think I heard was in Florida, and something happened and he sliced off half his hand.
Oh, it doesn't matter. If I try to replace a broken tile in a shower, you can bet that before the end of the day, the bathroom will be gutted, and before the week is over, the contractors are wondering how to fix it the destroyed room. If I try to repair a water leak ... well, do you remember the Three Stooges in the plumbing episode?
I do have the occasional home repair victory. Very occasional. And it's something on the order of replacing contact paper in the kitchen cupboards, where we have a big celebration when that gets done and the cabinetry emerges intact. My home repair prowess is rather limited to attacking clogged drains with the plumber's helper. I'm kind of okay with that.
Seriously, I hate home/mechanical repair. I know that some people enjoy it as a puzzle to figure out and conquer. And that's the appropriate attitude. To me, it's a straight line. I have a problem, and I want the singular answer to fix it. For instance: I have a bad starter, and I want to take it out and replace it. But to do that, there's a bar along the undercarriage in the way, and that has to be taken out, and one of the bolts holding it in is rusted and immobile, and not only that, but it's on the other side of a flange, which I can't get to without a series elbows on the ratchet, and ... arrrrrgghhhh!!!! I'm just not made for this stuff.
