There was a time when my risk-taking nature manifested itself in cross-country hitch-hiking, chemical ingestion and consorting with women of unknown provenance.
Now, I roll the bones by trying to nurse an ailing water pump to the weekend, and then taking my car apart in an effort to fix same without resort to an expensive technician. For some folks, working on the family heap is a hobby. For me, however, it's a scary challenge. Once you've got your engine disabled, you really have no option other than to go forward and able the damn thing. (Well, there's always the $65 dollar tow to a garage, the sheepish admission that you've screwed up your own car, the dismissive sneer of the mechanic, (aka The Guy Who Knows What He's Doing), etc. Well, my ego won't accept that manner of humiliation. I'd rather walk.
Fortunately, replacing the water pump is one of the tasks that can be done without resort to a lift, and my '91 Ford Ranger 4wd has enough ground clearance that I can get under it when necessary. It's not my intention to bore you with a play-by-play of the procedure. My point is that anyone can learn anything. And most of the time, (especially with access to the internets) you can teach yourself what you need to know. There is value in being able to do for oneself. We heat exclusively with wood from our own property. It's more work, but every log I throw into the stove is a great big "fuck you" to Exxon. We recently had the engine and transmission rebuilt in my wife's minivan; a big "fuck you" to Ford and the "buy a new car every three years" contingent. So when you see me covered with grease, or splitting a pile of firewood, don't admire my self-reliance; feel free to assume that I'm just saying "fuck you" to someone.
