It would mean crunching the numbers, but I don't think creative people are necessarily more prone to alcohol abuse than any of us other mere mortals. We just hear about them more often because they are famous. We all struggle with the creative life. Doesn't have to be a great novel or painting, or something.
Beware of false idols, I'm fully impressed with the bloke down the road who got sober. Think he was a very creative brick layer. He had a tough trot. And the cleaning lady up the road, could she ever swing a mop like a quill. Her life was pretty sad too.
Think it's a bit overrated the Dylan Thomas idea. We're all just people trying to get sober, but without the self indulgence of the artiste tragically creating alone in the garret without alcohol, barren.
Why do we put them in a different class to ourselves? All human beings are creative. Some just denied the chance.
I dunno, I'm raving on but will still post in the name of creativity, and the development of ideas.
