I have no problem spending the time / money learning something with no prospect of monetary gain in the future. Learning is an end in itself.

I feel there are 4-5 closely related topics that I touched upon but didn't dare delve into, because each one would be a blog post unto itself. The "survival" lifestyle is one of them. Living with learning as an end is another.
Ultimately, I feel that learning as an end is the theme of this post, without regard to an eventual monetary gain. The paradox being, of course, that true devotion (or should I say "pure" devotion) is only possible with monetary gain as a an end, thereby eliminating the joy of pure learning.
I would trust your own instincts and internal compass: if you are learning new things and feel "flow" when you spend time on this side project, keep at it. It will have some kind of impact.
One good article worth reading is Peter Drucker’s "Managing Oneself" (available here http://www.amazon.com/Managing-Oneself-Harvard-Business-Clas... and a little Googling may turn up other versions as well) where he stresses the importance of learning how you learn.
One good book on this is "The Three Boxes of Life" by Richard Nelson Bolles http://www.amazon.com/Three-Boxes-Life-How-Them/dp/091366858... which covers life work planning: the three boxes are education, work, retirement (play).
In my own case I have always been a connector and cross-fertilizer, trying to apply insights from one field or area to another, sometimes where they hadn’t been considered before. There are many narrow specialists out there, you should absolutely feel free to follow your Muse as long as you are learning.
