Do you keep a book journal? I first read about such a thing April of last year and immediately began one of my own. The journal I read about was begun when the woman was in high school and she has kept it up since then. I wish I had a record of what I had read in college. A few books stand out for me, but to be able to see them all would be a bit of fun from the past.
Even though I have begun this journal late in life, I look forward to looking back through the volume(s) in 20 years, remembering where I was when reading a specific title, maybe even deciding to read it again, in a new place, with a different outlook.
