Creating and Adding Value

This is the key to making $$$, no? The one common way to create value is to do what your boss tells you to do, if you have a job, as I soon will. But there are many more interesting ways to do so. For instance, I could add Google AdSense to this blog, and in 40-50 years I'd have the $100 balance necessary to receive payment. But what else?

This has preoccupied my mind for the last 5-10 minutes. It's not about the money; in fact, I really just want to display some entrepreneurial creativity.
