One reason I have trouble deleting titles from my list is that I think I will want the books later and not remember the titles. This is paired with an irrational fear that I will run out of books to read. On reflection, I realize that this is silly. There are already more books in existence than I can read in a lifetime, so for every title I delete there will be others to take its place. If a book is something I am just dying to read, I will most likely remember the title without having it on a list.
I also have this guilty feeling that I'm cheating if I reach the goal of clearing my list by deleting titles instead of actually reading the books. First off, this is my "game" and my rules, so I can do anything I want. Second, I have missed so many goals and experiences in my life because I insist on handling tasks in a certain order. As it relates to my reading life, this means that I often force myself to finish books that I am no longer enjoying, instead of chucking them and moving on. It takes me twice as long to read a book that I'm not enjoying, and that cuts into my reading time. Just this week, I made myself read at least 50 pages of a book that I wasn't enjoying, even though I could tell from the introduction that the book wasn't what I thought it was. Being a stickler for self-imposed rules that aren't working is a habit I am trying to shed.
Now that I've written this post and examined my thoughts, I think I should take a look at my lists straightaway and start culling unwanted titles while I have this renewed zeal!
