Personality Development: An individual's personality is an aggregate conglomeration of decisions we've made throughout our lives (Bradshaw). There are inherent natural, genetic, and environmental factors that contribute to the development of our personality; however, in the pursuit of a more defined persona, many individuals enroll in courses offered in colleges to further or enhance the image they intend to project to others. These classes assist in identifying your conscious traits and contrasting them with what you intend to exhibit. According to process of socialization, "personality also colors our values, beliefs, and expectations...Hereditary factors that contribute to personality development do so as a result of interactions with the particular social environment in which people live." There are several personality types as Katharine Cook Briggs and Isabel Briggs Myers illustrated in several personalities typology tests. These tests only provide enlightenment based on the preliminary insight scored according to the answers judged by the parameters of the test. Other theories on personality development are Jean Piaget stages of development, and personality development in Sigmund Freud 's theory being formed through the interaction of id, ego and superego.

The phrase is most commonly associated with the mid-1990s British singing group the Spice Girls. The group used the phrase as a slogan in interviews and on merchandise. Geri Halliwell (also known as "Ginger Spice") helped spread the phrase through her music, writing, and acting. In her music video, "Bag It Up", the phrase "Girl Power" was transformed into "Girl Powder", a product that transforms any male into an obedient servant. The Cheetah Girls also sing a song of the same name in the first Disney Channel Original Musical The Cheetah Girls. Some have suggested that the phrase "Girl Power!" mirrored the growing interest in popular culture in "The Girl" during the late 1990s. This interest was further reflected in the development of the academic discipline, Buffy studies. Professor Susan Hopkins, in her 2002 text, Girl Heroes: the New Force in Popular Culture, suggested a correlation between Girl Power, The Spice Girls, and female action heroes during the end of the 20th century. Hopkins explores the roles of Britney Spears; supermodels; Lara Croft; Xena; the Charlie's Angels of the 2000s; Sabrina, the Teenage Witch; Mulan; Charmed; The Powerpuff Girls; and Buffy in relation to the phrase, girl power.A few scholars suggested a specific link with third-wave feminism.
