I always thought of myself as kind of a cross between Stanley Richmond from Jericho (Big, honest, smart and dumb at the same time, kinda shy in an "Aw, shucks" way), Daryl Dixon from The Walking Dead (I'm a hillbilly, of sorts, tend towards seriousness, and have some survivalist tendencies), and Simon from Firefly (Pretty good at academics, and just the right combo of caring and manipulative/detached.)
Of course, all of those traits are strongly idealized in those characters.
