Jeffro - you will be sorely missed! I think that the distinction lies in the fact that you always wanted to "get the word out" about WordPress because you cared about it, and the entrepreneurial (building a business based on WordPress) side of it was something you let others do. In that regard, it is truly hard to make a full time living with WordPress if you're not doing full-time client work.

I wish you well! Are you selling the site?
