Jeanne Safer said this quote
“ Defining your own truth and then living according to it ... changes your sense of self and sets you free; it makes you fearless -- or at least more courageous -- with every significant person in your life. When you're not so insecure, there are things -- offhand cruelties, insensitivities large and small -- you don't tolerate, things you don't have to deny.... Once you are the one who determines the meaning of your life, nobody can gainsay it. This act of self-assertive defiance immunizes you -- at least to a certain extent -- from ever allowing someone else to control your destiny ever again. ”
