I know all about opportunity cost. What you need to remember is that it is market determined, and the market varies over time. The opportunity cost of my time varies between zero and a whole lot. Fortunately, I have enough hours when is a whole lot, but even more hours when it is zero. If that were not true, I wouldn't bother to build my own wheels, and I definitely wouldn't be posting here.
