One thing I learned and adapted from Naval Ravikanth (podcast with tim ferriss...google it) is to treat reading books like blog posts. So if I am interested in a book, I don’t have to start from the beginning. Just start browsing, open any chapter, read through it and continue if I relate with author otherwise close it down. You also don’t have to finish the book if you loose interest half way. Another unthinkable thing I do now is switch between books while reading them. Lastly re read books if you really like them. I read deepwork and when I finished I started it again right away.
