I mold myself to my surroundings. I only show the sides of myself that my instincts tell me are most beneficial to those around me. Co-workers get the professional me. Friends might get the goofy or generous me. Strangers might get the awkward me. Family gets the upstanding me. My wife gets the loving me... etc, etc, etc. I keep hidden certain parts of myself depending on who I'm interacting with. In that sense, I'm constantly changing; a social chameleon.
It actually makes more sense to me now as to why I've always struggled with my sense of identity. It was always hard for me to understand exactly who I am, what I want, and why. Even though I'm always searching for these answers, I've never found them. Perhaps there's a simpler reason for this: I'm essentially metamorphic.
