I try to bring elements of my own personality to every character I've played, but I think I'm pretty similar to the character I'm playing now. The biggest departure would have to have been Freaks and Geeks Sara, who was this sort of subordinate and shy girl.
She stops, pauses, turns to the left to glance at some possible threat or irregularity, and then continues to the north. This motion, so intensely human, transcends time.
