In addition to reading blogs, I am reading a couple of books at home and listening to an audio book on the way to work. This is not an original idea, but books are very much like friends. For a given block of time they have your full attention. You are “listening” to the author’s thoughts, empathizing with characters, sharing another person’s life (whether real or imagined).
I may lack for friends in the real world, but I have a full life in my mind.
