The enneagram is great, actually!
I first found out about the enneagram through Abbie Emmons, around three years ago, and I liked it as a writing tool... But recently, I've stumbled upon Typhoelogy's channel and I'm absolutely obsessed now!
Personality quices have always been a bit of a hobby of mine, but the enneagram is by far the most accurate I've ever seen. Nothing has ever made me feel as understood as researching about the subtypes and seeing all the complexities of this tool.
I'm still very much a beginner, but I'm excited to see how much more I can understanda about humans with this!
