Alfred Adler was an Austrian psychologist born in 1870 who developed the theory of Individual Psychology. Some key points of Adler's theory are that everyone is unique, behavior is motivated by goals rather than unconscious drives, and how we deal with feelings of inferiority influences our personality type. Adler focused on holistically understanding personality and behavior through three main life tasks: social, love-related, and vocational. He believed the way we approach these tasks determines our unique lifestyle and way of coping with feelings of inferiority.
