Who I Am In Six Words

Anytime I have to do any of the following, I get really nervous:
pick one word that defines who you are
pick one quote that shows who you are
pick one adjective that describes the essence of you
pick your favorite movie
what is your favorite song?
can everyone be reduced to such specifics??
This stuff drives me CRAZY. I can NEVER think of answers to these types of questions! And it has always made me feel bad about myself. As in, perhaps I have no personality and nothing about me is interesting at all because I have no answers to these questions. But actually, the older I get, the more I realize that it's such a great thing that I can't think of only one answer. On the more pessimistic side, though, I realize that I can't think of only one answer because I rarely tell the complete truth about myself to everyone. Most people only see one side of me. That makes sense with my students, of course. However, pretty much everyone who knew me in college probably saw me as an intellect and not much into socializing (if they noticed anything about me at all). My sons certainly have different opinions. As is typical, my husband is the one who gets the closest complete picture of me as a person. My current students probably think I'm a really strict grader, kinda klutzy, and sort of strange yet funny.  Is it okay that different groups of people only see certain sides of me? Should I try to change this? Does this make me a wuss of a person? Grow up...be who are you! But that is frightening.
Here are some attempts at answers:
okay, I've been sitting here for about a half an hour and I can't come up with anything original.
What I would want EVERYONE to know is that I want what is real. I can't stand having to wonder if someone is being honest or is just being polite or will later turn his or her back on me...the irony of this is not lost on me.
