3rd party view of yourself

Sometimes, the benefit of having someone who can evaluate you is that you get to understand what you should change about yourself, what you do, your personality, your characteristics, etc. And sometimes, I know that what I think is best and what I tell other people are two different things, because I want to be able to prove that kind of thinking through my own actions. Until I can prove it through my actions, I’m afraid that I can’t really tell other people to do otherwise
