When I was younger, I made a rule for myself to always be reading a fiction and a nonfiction book simultaneously, to keep my reading habit from being all fiction all the time. Now that I'm older, I keep the same rule, to keep my reading from being all nonfiction all the time. As it is, I probably read five or more nonfiction books for every fiction book these days. I don't know if it's about self-improvement so much as self-education, which seem a little different to me. For example, Deep Work is absolutely a self-improvement book, but Prisoners of Geography is simply educational. After reading Deep Work, I behaved differently (not differently enough). After reading Prisoners of Geography, I knew more, but didn't feel any different.
