In college, I took the Myers-Briggs Type Indicator. Typical personality inventory, right? Except I had to take it twice because my E (for extrovert) was 99%. It gave me career choices like Social Worker, Teacher, Retail and Food Service. Got it. What it didn't tell me: You will most likely be a little... well, unbalanced.
On a very related note, my social wrap-up after nearly 30 years: Sometimes you're a part of stuff, other times not.
(I had to stop seeing my counselor. Can you tell?)
