The thing about being good a boss and such if you're a shy kid (or not really kid but you get what I mean XD), I think it's true. I am very shy, but whenever we get into to trouble or such, I come up with a good solution, if I am the leader I know what to do etc.
(Now I am going to use an AoT example XD)
Armin, shy, smart, not that athletic,
he is a born leader when it comes to making up solutions, fighting plans, etc.
