On Owning More Books Than You Can Read is a piece that I'm grateful Jeff Miller wrote. So I don't have to.
Because I agree straight down the line. Except for the part about being a completionist. I have run into too many series that have lost their savor partway through.
On the other hand, the part about social media being wonderful for introducing me to new authors and books is especially true. Some of the best have been due to Jeff's reviews. And I tend not to have big stacks of books I haven't read. I guess that is my completionist element. If I own something I want to use it ... or read it, as the case may be.
