Yea, I agree with the guy who says that you are happier accepting that you are imperfect. I'm not saying that self improvement isn't admirable or that we should give ourselves slack and not others slack, but holding ourselves to the standard of perfection all the time is stressful. This is one of my problems- of course others hold me to a standard of more than perfection, which I can never reach which causes problems. I don't like people who hold you to impossible standards and then yell at you for not reaching them.
