deep in thought

Sometimes when your character flaws are pointed out to you, your whole world stops and you think. Think about what that person said and whether or not you agree. And if you do agree then what? Do you come to the conclusion that your not as great/nice a person as you thought you were, and if so how do you fix/change who you are. How do you know whether or not your changing for that person or yourself. And if your only changing for that person, is that good or bad?
