There are nine Enneagram types, and according to the Enneagram Institute, “it is common to find a little of yourself in all nine of the types, although one of them should stand out as being closest to yourself. This is your basic personality type.” The Enneagram symbol is ancient, and actually dates back to the writings of Pythagoras in ancient Greece, according to the Enneagram Institute. However, the personality aspect of the symbol wasn’t introduced until much later. If you enjoy taking personality quizzes on the Internet, you’ll want to take this test. After 10 minutes, you probably won’t be particularly surprised by the results, but that’s not a bad thing. Look at it as an affirmation of what you already perceive about ourselves. RELATED: What Your Birth Order Says About Your Personality While personality quizzes aren’t necessarily 100 percent accurate—because how can a test sum up one person completely—knowing your personality or traits could help you become more aware of your strengths and weaknesses. It might also help you improve your relationships, performance at work, and achieve personal goals. A little introspection never hurts! Take a look at the nine Enneagram types below and take the test at The Enneagram Institute’s website. 1: The Reformer This type is known as “rational and idealistic.” They want to make change and are well-organized, but sometimes that might mean they’re too critical or perfectionistic. 2: The Helper This is the “caring and interpersonal” type. People with this personality are friendly, warm-hearted, and want to help others, but “typically have problems with possessiveness and with acknowledging their own needs.” 3: The Achiever This type is “success-oriented and pragmatic.” These people are highly ambitious and charming, but they might become too obsessed with success and their image. 4: The Individualist Known as the “sensitive and withdrawn” type, they are “emotionally honest, creative, and personal, but can also be moody and self-conscious.” 5: The Investigator These types are “intense and cerebral.” They are innovative and inventive, and can come up with high-level ideas, but they might be seen as detached or intense. 6: The Loyalist These people are “committed and security-oriented.” According to the Enneagram Institute, “they foresee problems and foster cooperation, but can also become defensive, evasive, and anxious.” 7: The Enthusiast This type’s name is pretty much self-explanatory—they are extroverted, spontaneous, and always looking for new experiences. However, they can be impatient, impulsive, and over-extended. 8: The Challenger Known as the “powerful, dominating” type, the “Challenger” is self-confident and assertive, but can be temperamental and domineering. 9: The Peacemaker People who are this type are “easygoing and self-effacing.” They are accepting and supportive, but that can lead to them becoming too complacent.
