After 12 years working in a corporate environment, I'd come across my fair share of personality-typing tools.
I loved the opportunity they provided for learning more about myself, and I usually experienced many "yes - that's me!" moments. But the insight never really translated into action. Nothing really happened after the workshop. And nothing really changed in our team.
That is, until I experienced the Enneagram... I realised very quickly that it wasn't simply a personality-profiling tool. It dug way deeper than anything I'd done before.
