Realization of ones own simplicity

So, I decided to read a few blogs before writing another bit of trivial nonsense and came to the realization that I am a very simple person. People write about religion, the economy, the environment and I write about feelings and random thoughts. I try to give my attention to these blogs but it resembles reading textbooks in school. I never was very good at that, having to read and reread to get the information into my head. Does this make me a useless piece of flotsam in this world? Actually, sometimes when I become aware of the amazing volume of lives on this planet this is a feeling that arises. What am I but a bit of driftwood on the huge ocean of life. Just floating hither and yon wherever circumstances push me. Of possible use but one might never know unless noticed and retrieved for use of some kind. Hmmmm.
