I’ve spend stupid amounts of money on books in my life. When I wanted to learn about a topic, I’d go to Amazon and order the top 5 to 10 books in its category. If I saw a book referenced in a few papers on science I read, I’d add it to the cart, and buy it the next time I ordered a stack of 10-20 books.
I figured it was better to have books lying around unread than to miss the opportunity to read on a topic when I was inspired. Books piled up on history, governance, economics, investing, finance, marketing, business, psychology, biographies, time management, habits, willpower, discipline, creativity, writing, selling, publishing, technology, innovation, philosophy, and, umm, lots more. Fiction too, though I didn’t read fiction for a while because I thought it was a waste of time. (I was mistaken on that point.)
I’m the same way; I have probably 30 books on my shelves that I still need to read. I made a prioritized list, but have to keep adding newly bought books to the top. It’s nice to know that I’m not the only one out there like this.
