This is an ongoing process of self-evaluation, identification, development of existing characteristics, assimilation of new characteristics, beliefs and personal twists. No one person can ever complete this process. It is continual and ongoing. Every moment one lives they will come across another piece of the puzzle, no matter how small it may seem. This evidence must fit in some way and should not be ignored. Know Thyself includes unlearning. For unlearning one must be able to recognize when they are wrong, acknowledge that and implement the appropriate changes. Someone people will admit when they are wrong to the other people, others will not for their own reasons. Some may be justified, others may not as I believe there are times when both are needed. But the important factor is that such invalidity is corrected to the best of ones knowledge, whether part of that correction involves admitting to others or not is only one consideration, but important nonetheless.
