Elizabeth Wagele (1939–2017) was an American artist, musician, and writer of books on the Enneagram of Personality and the Myers-Briggs Type Indicator (MBTI).

Music played a major role in her life as a friend and spiritual guide, especially Bach, Beethoven, Brahms, Bartók, Charles Mingus, Billie Holiday, and other classical and jazz composers.

Wagele included a section on the movie Napoleon Dynamite, along with chapters on relationships, children, Jung, neurology, personality, and creativity.

Wagele sheds lights on differences between extroverts and introverts (25 to 30 percent of the U.S. population) and introduces main points of the fascinating personality survey, the Myers-Briggs Type Indicator.

[14] David Daniels, Clinical Professor, Department of Psychiatry and Behavioral Science Stanford Medical School, and author of The Essential Enneagram called The Career Within You "a groundbreaking work."

He described how the book provides for nine personas "thoughtful and clear descriptions, how each style relates to the spectrum of career choices and a powerful method to determine the path that best fits you.
