Few thoughts came to my mind while reading your post:

• After looking at the picture, I was wondering that how you captured this simple log. You must have a real sense of photography.
• Your observation is very sharp. Like, how many people would pass by this hollow piece of a log but nobody looks at it in the way you did and extracted so many lessons. You way of seeing the things is totally different in a good way :)
  Everything has a fall, so why to be arrogant over what we have. Be humble and enjoy every moment. :)
