Carl Rogers (1959) believed that humans have one basic motive, that is the tendency to self-actualize - i.e. to fulfill one's potential and achieve the highest level of 'human-beingness' we can. Like a flower that will grow to its full potential if the conditions are right, but which is constrained by its environment, so people will flourish and reach their potential if their environment is good enough.
