Many thoughts and possibilities are roaming through my brain on this one. I can think of pairs of people to compare, one with "better within," one without. I don't feel like writing about that. I think you, dear reader, most likely can come up with an example or two on your own.
None of us know another well enough to know what has made their "within" be such as it is. Suffice it to say that it behooves us to choose to make our "within" better, because we live and act organically from that "within."
