Myers Briggs? I'd say yes, absolutely. Horoscope just takes into account when you're born, but Myers Briggs is an intense questionnaire that asks about your behavior and preferences. It's taking what you tell them about yourself and forming a general profile about how you respond to the world. It used to be pretty popular to do them for work-related assessments as FS pointed out.

I'd say many people find them quite accurate. Of course we still have free will...it's not like they tell us how we will act in the future.

FS: I used to be an INTJ. I switched several years ago when I took the test again. I must be on the cusp. You and I can go off and rule the world together. Can I pet my evil-looking rabbit? I prefer them to cats.

I've never done Reiki. I love how it works for you, and I'd be curious to try sometime.
