Perhaps our flaws are gifts in disguise, and complete acceptance of who and what we are is a key element in ridding ourselves of the tyranny of our history. It could be that what makes our history such a sticky part of the present is the painful remembrance of times when, in being ourselves, we were rejected and/or rebuked. We go forward into our future trying to avoid similar pain by acts of self rejection, self improvement, self hatred, and self denial. Perhaps if we practice total self acceptance it will help us integrate the parts of us we abandoned in the past when someone undermined our value and worthiness by telling us we were not as we should be.
We are and have always been exactly as we should be.
