This world has been designed to teach us something every day that will help us better ourselves. We just have to look for it.
It can be as complex as the book we hear about on NPR which makes quantum geometry accessible; or, it can be as simple as seeing a child learning to walk fall seven times but get up eight. The lessons are there and they improve our lives.
It is the way The Creator designed it; the simple act of looking for these lessons allows us to see them.
