In general, I think it's important to know how to describe yourself. Do you describe yourself as your circumstance, your job, your home of record, your faith, your character, your characteristics, marital status? How do you want others to describe you?
I refuse to be defined by my job...b/c i'm so much more than my job...but i sit back and think, that's probably how other people describe me. In conversations, I always avoid occupation & education unless it relates to other subjects.
Yet, somehow, if i become a Peace Corps Volunteer...that is how I will be introduced to my community members, and after service I will likely describe myself as a Returned Peace Corps Volunteer for the rest of my life. I would be proud of this of course, but i think i like the idea of describing myself in terms of my future, and not my past
"Hello, my name is Liz & I'm a future Peace Corps Volunteer" --I can't wait to start use it!
