Mastery, Robert Greene, page 84

Let us state it in the following way: At your birth a seed is planted. That seed is your uniqueness. It wants to grow, transform itself, and flower to its full potential. It has a natural assertive energy to it. Your life’s task is to have a destiny to fulfill. The stronger you feel and maintain it - as a force , a voice, or in whatever form - the greater your chance for fulfilling this Life’s Task and achieving mastery.
