How many blogs can one person have?

I am starting this blog not because the world is in desperate need of another, but because it may force me to write on this topic.

Some years ago I worked for a convenience store chain.  In the course of my duties there I had occasion to come in contact with the concept of cost accounting.  I was particularly taken with the differences between retail accounting and cost accounting.  I came to greatly respect this latter approach and began to apply its concepts to a great many disparate areas.  This blog will hopefully explain some of that thinking.
