The Four Tendencies

I have very mixed feelings on this. First of all, I wouldn't recommend this as a first look into personality types by any means as this is seemingly not based in research at ALL. The author is not a scientist or doctor and has no real qualifications to create four personality types, but has done so based on personal opinion and observation. So I took the whole thing with a grain of salt and would suggest anyone else to do so as well.
That being said, it has been interesting to me to consider how my “tendency” and those of other people in my life might affect my behavior, relationships, way of thinking, etc. This was really just more of a thought project than anything, and it did indeed get me thinking. But I'd like to dive further into similar thoughts that have real research to back it up.

And as a huge side note, she completely missed the meaning of Taylor Swift's Shake It Off. “I stay out too late, got nothing in my brain,” is sarcasm, Gretchen. If you don't know what you're talking about, don't say it. :)
