@The Pentacle Queen,
I'm an engineer. I studied Aerospace Engineering, but I currently work as a Systems Engineer.
I am fairly fresh out of college, so I can speak to the nature of what college gave me and what it did not give me. It is difficult for me to calibrate my language on what I "know" vice the layman's knowledge on the topics I studied.
To be blunt, there is nothing that I'm the best at, and when compared to other individuals who have much more experience than myself, I feel the gap between me and them is equivalent or greater than me and the layman.
It may be premature for me to answer this question. The things I feel I'm best at, are not things I learned in school or in my profession. I'm talented in public speaking, mediation, and problem solving. I don't fully understand or clearly vision what the layman's understanding of those topics are, so it's hard for me to distinguish what others might not know.
I think my math and science proficiency is higher than the layman's if that counts...
