In the past there was a time when I was a bit crazy about keeping track of what I read, first on Goodreads, then on Booklikes. I said goodbye to Goodreads (too many negative vibes) and still use Booklikes, but not in the same way and extent I did maybe a year or two ago.
Then I was taking reading and everything that has to do with it too seriously, everything needed to be kept track of, nothing was spontaneous, everything followed certain rules I had decided to stick to.
Since then I learned that this was one of the points that took away some of the joy of reading, that constantly keeping track of book related things made everything a bit too clinical for me. I still keep track of the books I read, but don't feel bad about not updating my list every week. The last time I updated my shelf on Booklikes was about two months ago and I'm still relaxed about it. I plan to do an update soon, but I'm not worrying about it any longer and this is what counts for me.
I'm now relaxed about reading and everything that has to do with it, I no longer stress myself out because of minor things, I concentrate on the pleasure books give me.
In the past I planned to use a journal to keep track of the books I read, I already have a journal at home, but so far I haven't used it. But the plan still exists.
Btw, after writing my first "In retrospect" post on review copies, I realized that these posts help me to sort my thoughts, help me to let go of some things that bothered me about reading in the past, that made reading less enjoyable for me, so you can expect some more of these posts in the future.
How serious are you about keeping track of what you are reading?
