Nietzsche and Adler “will power” are two different meaning, Nietzsche believes that will power is manipulating attitude or character of fragility and frailty, it is a supremacy, a pamper to one’s self with appreciation and it means an admirable traits of the good ( to be like by everyone) by the approval of others. While Adler believes that “will power” everyone should be treated equally and everybody should performs and act to better their surroundings and every person around them. Adler’s outlook would be the happiness to the greatest number of people because you’re not doing it just for yourself but you’re doing it for the equality because that’s what you believe in.
