I complain, my parents complain, my brothers complain, the dogs complain when I put them to bed, my friends complain, my relations complain… Everyone it seems, at some time or another.
Maybe, the next time one feels a complain coming along try to direct the complaining energy into doing something nice for someone else. That way we would feel better about ourselves, make someone else happier and be directing our energy into being a radiator rather than a drain.
