Lots of people have some personal thing they're spectacular at: remembering birthdays, or organization, or personal style (someone who always looks splendid, and she's fun to boot! I envy her style skills while accepting that I will never be that person), or caring and empathetic (another friend who is always unfailingly kind).
Mine is robot feelings. I have lots of feelings, obviously, but they don't need to influence my fact-based decisions. Also, other people's feelings make me uncomfortable (in professional settings). GOALS are important. Turning in grades on time is important. My dislike for [staff person] is irrelevant. Everyone else's dislike for [staff person] is irrelevant. Fire [staff person] or stop talking about it.
Or, to be more accurate, I am half-Vulcan.
What's your excellent personal thing?
