Of course we do want to be perfect in all we do, but as they say, no man is perfect. It's difficult to be perfect, maybe when you do, it might be on one or two occasions.
We have people who will criticize you even when you are perfect, no matter how hard you try, it's never enough. many of us feel terrible in the end, after not being appreciated. All we need to know is your own definition of perfection may not look perfect to someone else. So just do the best you can and let it be.
