Reading is a balance - not reading in childhood is missing out. Reading too much as an adult is running away from life, much like TV and video games. On the other hand, I am reading the Three Body Problem now, and I am learning some history and being forced to remember scientific principles I didn't review since high school. So I guess the lesson is quality and not doing too much of it. I stopped reading sci-fi that didn't win the Nebula (or whatever it's called) award. Just not worth the time.
