Why Do I Blog, Anyway?

I was recently asked why I blog, and I'm happy to oblige with a reply. First of all, you'll notice that I framed this as a request to ME instead of it being part of a larger project in which several bloggers will participate. This should give you some idea of where this post is going.
I came to LA in the mid-eighties, to break into showbiz. I had a powerful creative urge then and I wound up writing 11 screenplays in addition to doing improv and trying a career as a video editor. After a while I decided enough was enough. I was losing money on the attempt to break in, and putting all my energy into the life I wanted instead of the real life that I had. I forswore all creative expression.
It lasted about a year.
Here's the thing about blogging - I have to write. And blogging allows me to write with a low impact on my life, while netting me a potential worldwide audience. If that audience is, in fact, half a dozen people, that's still about twice the number who read the screenplays. And if I'm not making money blogging, I'm not losing any either.
So why do I blog? It's all about me, about my needs. The great thing about having the entire globe as your potential audience pool is there are plenty of people out there who might still enjoy it. In the mid-eighties I couldn't have imagined anything this impossibly cool.
