I'm both too! I decide what I want to buy, do the homework, especially if it's a higher ticket item, but I get impulsive after I've done the pre-planning because once I spend all that time thinking about what I want, I usually buy it whether or not I should, lol.
Great blog, Sandi! Too many choices is both a blessing and a curse, isn't it. I wish I had the answer. Possibly you could schedule in more reading time???
I'm very aware of covers and often look at them as I read to see if the descriptions match. If they don't, it can actually slow me down as I try to get the images in my head realigned, lol.
Like others here, I'm often disappointed with the movie if I've read the book first. As much as I love movies, they rarely explore and reveal character the way the books does, so it often feels as if something is missing.
what's fun is seeing a movie you love so much that you run out and get the book. I did that with The English Patient and several other movies.
