I very much support the notion of taking personal responsibility for being the change as opposed to critiquing others. Critiquing others, especially unasked for critiquing, doesn't help. Be the change you want to see in the world is Gandhi's message. It makes sense to me. So does the Golden Rule. Both seem to be very basic wisdom to live. I often live by the Golden Rule, being considerate, compassionate, and taking responsibility for my behavior, and usually don't censure those who aren't (except in my head, which is its own problem). What helps me stay rooted in setting a good example is knowing that I can only change me, knowing that how I am affects others, and knowing that my right action is its own reward no matter what happens.
