Books, that is. For many years, I've been a one-book-at-a-time reader, always finishing one novel (or giving up on it) before starting another one. This wasn't always the case. When I was a kid, I would often be reading three or four books at the same time and had no trouble at all remembering what was going on as I bounced from book to book, reading whichever I was in the mood for at that moment. Somewhere along the way, though, I stopped doing that.
Now, with my limited time and attention span problems that were making it difficult for me to read novels, I decided to give the old method a try again, and to my surprise, it seems to be working. I currently have three different books going. I tend to concentrate most of my reading on one of them, but I don't hesitate to pick up one of the others if the mood strikes me. In fact, one of them I'm reading as a sort of serial, a chapter a day. This isn't the way I plan to read books from now on -- I'm sure I'll go back to the one-at-a-time method sooner or later -- but for now it's been a welcome diversion.
