Having a realistic sense of self is great; diminishing your self into a nothingness (i.e. totally altruistic) is not something to be admired. Then again, maybe I've read too much Ayn Rand.
True, I re-read the article and see it now, and agree 100%. However, I still think "I am nothing" is a poor turn of phrase for it. I would prefer "I cannot be labeled" or "I am none of the above".
