It all depends on why I am reading a non-fiction book. I much prefer a good fiction since I am not longer reading for school.

There was a time when I read a lot about finance. I had to make some decisions at work regarding benefits and I wanted to be well informed. I used the old yellow marker in those books. They belonged to me and I still occasionally check them out.

I went years without reading non-fiction and then my daughter suggested Quiet:: The Power of Introverts in a World That Can't stop Talking by Susan Cain. I got it in audiobook and just loved it. I've known for years I was an introvert and suspected as much about my son. I could see us both in places in that book.
