Enneagram numbers are a way to categorize what your personality type is, and for Enneagram Five, their characteristics include working alone, asking questions, and being the “investigator.” As an Enneagram Five, you probably already have a stack of books by your side, but these are some book recommendations to add to the pile.
"The Brain That Changes Itself: Stories of Personal Triumph from the Frontiers" by Dr. Norman Doidge is about how keeping the brain occupied helps with its neuroplasticity since Enneagram Fives love to “be capable and competent.” This book will teach you how to maximize productivity and how developments in the brain have changed people’s lives.
If you are very introverted and ‌reject social interactions, read “Talking To Strangers: What We Should Know about the People We Don't Know" by Malcolm Gladwell. Gladwell explains in his book how to talk to strangers to avoid conflict and genuinely connect with one another.
Your mental capacities can be an extraordinary gift, but can also be a trap when you use them to retreat from contact with yourself and others. Stay connected with your physicality,” the Enneagram Institute advises. Read Chip and Dan Heath's book "The Power of Moments: Why Certain Experiences Have Extraordinary Impact" to discover more about this approach.
