Since I am an INTJ, I have a confession, my ISTJ best friend is killing me. I used to have some serious down in my life and I turned to her, somehow, she is so dedicated in the business to help me by talking about other people's motivating stuff and sending me things like "Chicken Soup", and I don't want to let her feel that her effort is nothing, so again and again, I said that I really appreciated that, so somehow, I am wearing a mask all the time and I knew that some day I will crack.
