There are 12 key personalty types (these are called archetypes) and they are useful for more than just putting a label on you. Understanding who you are (your archetype or personality) is essential to improving your brand, who you work with, and your overall relationships with people.
The term “archetype” has its origins in ancient Greek and is as old as storytelling itself. But it was the early 20th century psychologist, Carl Jung, who brought the idea into the modern world. He used the concept of archetype in his theory of the human psyche. Jung suggested that our unconscious thoughts and behaviors could be explained by age-old stories that all humans understood—stories that date back to the earliest instance of human consciousness.
