I actually accomplished reading a book a week in 2015 and although my techniques and methods were different, at a high level, this is a great summary.
I used a Kindle e-reader and the Amazon wishlist. Put books on my wishlist and then proceeded to buy atleast 2 at a time so that I dont have to wait for the book to be shipped.
I also used my commute time. In fact, I carried my kindle everywhere in case I ever had to wait — when someone was late to a dinner meeting or I need to wait in line to buy tickets.
