Relearning the art of seeing the world around us is quite simple, although(a)it takes practice and requires breaking some bad habits. And "relearn" isthe correct word. Most of us observed much more as children than we do asadults. A child's day is filled with newness and wonder. The desire to explore,to have an adventure, gave us all a natural ability to be aware of the worldaround us. But as adults we are slow to be stimulated by new ideas and newsituations. We fail to see the wonder of the things around us.
