Focusing on a book has become challenging, with my mind easily wandering.
In recent years I have found this to also be the case in my own life. I've been a reader from the time I was a small child. These days I'm more likely to listen to a podcast or listen to an audiobook. Yet, I still buy books. I buy them and put them on the shelf. Buy the audiobook and listen to that instead. I'm an author's best customer because I already know I'm buying the physical and audio versions of their books.
I have a bunch of audio books I never got around to listening as well. My trouble has transcended formats.
