I agree in terms of the economics of it for many readers at least. I buy a lot of books. I would buy a lot more e-books I think if prices were reasonable i.e sub $5, vs. usually being as much a print copy. I also gift many books. I recently downloaded 200+ books via b-ok.org...most of which I certainly wouldn't have bought and probably half of which I won't open for years if ever. Two months later, though, a couple of the books I enjoyed that I've ordered new copies to be sent as gifts as friends.
I would be a good candidate for something like Kindle Unlimited, but most of the books I'm interested in aren't available there. At least half the books I downloaded (many academic as well as poetry and other books) are not available on Kindle Unlimited.
Subscription music aggregators seem to have a pretty decently comprehensive offering in a way that the book, news, and movie aggregators don't.
It would be a little weird, but if there was an app where I could read any book but every 20th page or so was some full page ad...I could live with that (as long as it wasn't a video or something). Not sure if that kind of a model could work in terms of the economics for writers -- but it's of course working for news mostly and for some film sites like Tubi and Pluto.
Not sure...so just throwing out ideas here. Perhaps try meditation for 20 minutes or so a day and twice daily exercise to help too. Maybe go off the Adderall for a week or two...try to step up the meditation/exercise (maybe coffee too)...then try the Adderall again? Or take it less frequently, like 4 days a week?
