Rabbi Zweig explains that surpassing the expectations that have been defined by one's social upbringing is what gives a person a sense of accomplishment. If a person is able to identify their lineage, they might learn that their ancestors were people who took responsibility for themselves and had honorable standards. For the rest of the world, the very act of taking responsibility is in itself an elevating sense of accomplishment. However, behaving responsibly is not considered an accomplishment for G-d's chosen nation. Jews are EXPECTED to behave differently than animals, to act responsibly, for our forefathers have set a standard that makes anything less unacceptable. This explains why households were important enough to be counted. The Ramban (Nachmanides) enforces the lesson of our Parsha by explaining the use of the Torah's language: The alternative meaning of "lifting" of the heads can also be a positive, but only if the body and its actions are lifted with it. Our heads and minds can lift us to greatness, so long as we have our actions to take us there!
