I posted the following on the "Books from XJW" thread. I think the same thing applies here, just substitute "Activism" where I wrote books. Anybody who thinks they can make a living off being an XJW is probably deluding themselves. The target market just isn't big enough to support somebody full time. And at some point the information some one has will reach its "sell by" date. I stopped going to the Kingdom Hall in 1988. My personal experiences are now thirty or forty years old. If somebody wants information about the good old days I can supply that. I wouldn't expect to be able to sell it, any more than I can make a living selling stale bread.
Here's what I wrote on the other thread.
World wide there are not enough people that care about JW's for books to have any impact. I don't think I'm a bad writer, I looked back at my Amazon account, my alternate history trilogy has sold almost 4,000 copies in all formats. My mystery/suspense novel based loosely on my time as a JW ("Armageddon's Disciples") has sold three.
As witnesses we were taught that our religion was at the center of all human history. Like every thing else the Watchtower told us, that is wrong. I don't believe the Witnesses have had any impact on the rest of human society. The closest they've come so far is a few supreme court cases in the US, and even most Americans don't know much (if anything) about that.
