No, I'm NOT perfect -- I don't claim to be. I've always been taught to "do the best you can". In my book, that means that we all "strive for excellence", knowing perfectionism is out of reach. Anyone who claims she doesn't make mistakes is not doing anything, and that's the biggest mistake of all.
I am happy if I'm doing the very best I can, always striving to improve, always striving for excellence, not perfection.
