Interesting question, Dotsie:
[Confused] Maybe cause the world is so accustomed to us giving and giving, that when we don't give as expected some put us down.

[Razz] Maybe cause we, ourselves, expect too much of ourselves and get frustrated when we don't accomplish all we set out to do...
Instead of looking at all we've accomplihed, we "beat" ourselves for lacking something?

[Wink] Maybe some never got the recognition and encouragement while growing up and that helps us not feel good about ourselves?
