To trust one's mind and to know that one is worthy of happiness is the essence of self-esteem.
Nathaniel BrandenIn a world in which we are exposed to more information, more options, more philosophies, more perspectives than ever before, in which we must choose the values by which we will live (rather than unquestioningly follow some tradition for no better reason than that our own parents did), we need to be willing to stand on our own judgment and trust our own intelligence-to look at the world through our own eyes-to chart our course and think through how to achieve the future we want, to commit ourselves to continuous questioning and learning-to be, in a word, self-responsible.
