Attaining perfect is the goal but then even if we attain perfection in something we still tend to tell ourselves that no one is perfect and that gives us room to make another mistake over and over.

She calling you a perfectionist was because she saw something of such in you, a perfectionist is not someone that is perfect take note but someone that wants to achieve perfection no matter what. So I don't think is a bad thing to be addressed as a perfectionist, although it might be in some cases but then we shouldn't take it as an insult, we should just be happy we working hard to get things right.

If any one is addressed as a perfectionist that shouldn't make such person above corrections, he or she can still be corrected and their ability to accept these corrections and keep getting better at being the best of themselves.
