You are elegant, withdrawn, and brilliant.
Definitely not the first one, the second yes, and I don't even know what the third is referring to (really, brilliant? At what?)
Your mind is a weapon, able to solve any puzzle.
Yeah, my mind tells my hand to use a hammer. Puzzle solved.
You are also great at poking holes in arguments and common beliefs.
Can but don't. It's irritating and boring; acting contrary to said beliefs is much more fun.
For you, comfort and calm are very important.
Yes. For staying out of prison.
You tend to thrive on your own and shrug off most affection.
Except replace "most" with "all."
You prefer to protect your emotions and stay strong.
Um... maybe? I'm not even sure how to "protect" an emotion. Wasn't aware they could be damaged.
