I found out that it was tons of fun, and not quite so hard on me as picture making has tended to be for some reason. So I have continued doing that as well. I've written a couple of novels, not yet published, and have a few short stories published, mostly science fiction and fantasy. Now I have all the stuff on my own sites and several different places on the web. I have dabbled briefly in music, and I will not leave this mortal coil until I have done both music and films professionally, too.
Some people advise others to specialize.
I imagine they said that to Leonardo da Vinci also. Not to compare myself to him, he was an excellent sportsman too, for instance, which nobody ever accused me of being. Thanks for the thorough discussion.
