People are convinced I'm good and I suppose it's true on some level, but I have feet of clay and know it all too well. Given this reality, it's hard to be too self-congratulatory.
A sense of "goodness" for me stemmed from many sources...spirituality, yes, but simply observing what works and doesn't work (in the long term) has been a good teacher, too. Especially because I have occasionally had to (as have most of us I suspect) do something that someone might consider "not good" (or certainly not their preference) to accomplish a more holistic good. Ya can't please everybody and that's just the way it is.
