I'm extremely busy. I have a 2 year old my wife and I both full time on opposite shifts because of no child care. Needless to say, my reading was suffering.

I got into audio books and it's been really great. Audio books might have lower comprehension than reading from a screen or book, but if you have a low attention span it's probably better.

I figured out that you get two books from audible if you do a trial and there are a bunch of Marxist audiobooks floating around. I'm sure if you look around some kind soul has uploaded from audiobooks of anarchist works too.
