Do your Human Design profile and see how much it fits.
Our society expects everyone to be a Generator (in HD terms) - all people who are not then feel like they're totally weird. In reality, they're just wired differently, and have other strengths and weaknesses.
Humanity is like a big puzzle piece.
As someone who never was into astrology, Human Design was a shock.
I didn't want to even consider that idea at all, but as I got my design read by someone I never met, and it matched 95% of what I already knew about myself, I had to admit that it just fits. And so it is for most people - it fits.
Whereas astrology always was a lame 50/50 "could be true or not true" kind of thing. HD is different.
For example I have open head centers - in HD this means I take in thoughts from others and get carried away with them; I also have an easy time to still my mind and have no inner dialogue. And in my life I had already observed if I am talking to someone who is genuinely really excited about something, I get excited about it too - to the point where I am joining their project or decide to buy a book etc - but when they leave and it wears off I am thinking... "wait... why was that so exciting again?"... Now I know how to watch it, and how to distinguish their emotions and thoughts from mine, very useful skill.
