I love this article --

As a fun aside, I am meticulous about trying to learn every little detail I can about problems that arise with both my car and my house (it drives my wife crazy). I am an extremely "unhandy" person, but I still love giving it a go.

This has led to the following two most common scenarios:

1) I fix the problem at hand after some trial and error, saving lots of money on an expensive service call (fixed a leaky sink, repaired a lawn mower, etc).

2) I make things (way) worse, thus costing a lot more money than it should (my car's exhaust system, the sewer line from our house, etc).

I'm likely sitting at a zero sum; all well worth it.
