I love to read but many of the books I 'read' these days are audio books because of how much I travel for work. My reading habits are a bit chaotic, and it seems I either binge a book in a couple weeks or take years of stopping and starting. I love to learn about and read history, science fiction, biographies, essays, politics, philosophy, popular science, and more. Recently I've become interested in reading classics too.
I consider the day a book is acquired to be when I start reading it. This is mostly for motivational purposes, otherwise I'm liable to forget let the book sit on a shelf.
I love the concept of Bookyrm, and after tracking my reading in spreadsheets for the past 5 years I have now moved it all to Bookwyrm.
