There's a lot of talk about self-esteem these days. It seems pretty basic to me. If you eat to feel proud of yourself, you've got to do things you can be proud of. Feelings follow actions.
I can't do everything but I can do something to help somebody. And what I can do I will do. I wish I could do more.
If you want to feel proud of yourself, then do good. Take action that will make you proud. . . . And if you really want to feel proud, then do something to help someone else.
