Hmm. I suppose there's one friend I have who inspires much of my personality. We're not at all alike, (although I do love her sense of fashion) and she doesn't realize it, but by observing her, I realize that as a woman, I just don't have to give a damn about how I act, what I do, and what I think.
As for everyone else, what they vocally think often inspires me to keep a non-judgemental perspective on things. >.<
