I write about what interests me.
I wrote 10 articles over 35 years and 35 articles over 6 months here. My first article paid the most, about $2,600 in today’s dollars, and sold over 10,000 reprints around the world in the days before the internet. That’s like getting 10,000 fans on a single article.
I do it for fun and don’t expect 10,000 fans.
