Another change is I’ve stopped worrying about “completing” books. I now take a “subject” and read about 2-3 books (along with several articles) on it. It gives me multiple perspectives, sort of climbing a mountain through different paths. For instance I developed interest in 2008 credit crisis and am reading 5 books.
That said if you really can read faster and retain the content then it’s super amazing. But it wasn’t for me.
