If you are not familiar with the personality-typing tool, The Enneagram, try this brief test and see if it rings true for you. The same website also offers a battery of similar tests, if you're interested in more in-depth assessments.
Beyond just the nine basic enneagram classifications, I wanted to introduce a brilliant book that takes the types into a realm of spiritual self-transformation: The Spiritual Dimension of the Enneagram by Sandra Maitri.
From the book's introduction:
"The recently deceased Sufi teacher Idries Shah recounts a parable that I have always used when introducing the enneagram. It tells of a tinsmith who was unjustly imprisoned and who, seemingly miraculously, made his escape. Many years later when he was asked how he had done it, he replied that his wife, a weaver, had woven the design of the lock to his prison cell into the prayer rug upon which he prayed five times a day. Realizing that the prayer rug contained the design of his cell's lock, he struck a deal with his jailers to get tools to make small artifacts, which the jailers then sold and profited from. Meanwhile, he also used the tools to create a key, and one day made his escape. The moral of the story is that understanding the design of the lock that keeps us imprisoned can help us fashion the key that will unlock it."
