There are many who say “You can be your own worst critic.” However, no one knows you more than yourself. For many people, the feeling of dread overtakes or creeps in when asked to describe or tell about self. I believe this happens due to the lack of really not knowing self. Could it also be that many feel compelled when asked to do so? I find that there are people who draw away from talking about their person especially if one feels forced.
For those who do have reservations in describing how they see self, take the time to evaluate self and examine life. In your observation, you may see how you overcame an obstacle that was hard to overcome. But, with the strength you thought you did not have, gave you triumph over the obstacle and that shows one has tenacity.
