I stopped reading fiction abruptly one day a couple of years ago. I still love reading, but I have to force myself to read any fictional novel. When I do force myself to, because the story sounds very interesting, I never regret it & always enjoy it. But when it comes time to choose more books, I’m back to only wanting to read non-fiction. No idea why.
When I read fiction, it is mostly classics including works from the 20th century that are regarded as classics.
Browsing in bookstores these days is more a behavioral tic for me than anything else. Forget about fiction.
