No fear in that, I earned my living as a theater director fifteen years, before the writing became a full time gig. Now, the goal is to move from writing what others need from me, into writing what I want to put out into the world. I have a huge catalog of "unplayed symphonies" in my hard drive, so, I'll dole those out here as long they keep reading it.
What I teach is this, the difference between a "writer" and an "author" is that the author finished something. That, in my experience as a lifelong arts professional, is that this is the dividing line between those who practice their craft, and those that dream, but never do.
I am preparing myself to accept that this platform will change eventually. I love your perspective on this, it's nice to be far enough along in life to take it for what it is today and not worry too much about what it will be in the future. I am curious, but as long as we leverage what we build here into audience, the rest can work itself out, whatever platforms there are in the future. Keep writing my friend, I'm glad you are finally getting some reward. It feels good to earn from what you feel like you were made to do, doesn't it?
