My own personal caveat to personalty assessments: when relying solely on your own answers to the bubble tests, sometimes you may get a "false positive". You unconsciously "trick" the test. That is, if you think you are an extravert you may answer questions "as an extravert". Okay, that may not happen to everyone...but has absolutely happened with me. I've found that if I take any assessments for work that I answer all in my "work" persona which is very different from my "private" persona.The most memorable question Beth asked me was: "When you have a really horrible day, maybe at work, or your feelings are hurt, do you want to go out with friends or go home and be alone?"
Me: "Home." (and then I wanted to add...doesn't everyone?). Turns out that this is a specific way of "processing" and not everyone processes everything the same.
I know I've just stated the obvious but it's not cliché.
Having a better understanding of my natural ways of seeing the world and my natural ways of processing information and emotions has helped me have many "aha" moments. I'm still enjoying exploring this.
