If one is to make any resolution at all, does it make more sense to resolve to do or to be?
It can be argued, of course, that there is no difference between the two because being consists of doing. The counterpoint is that being is broader and takes in a multitude of behaviors which, if not addressed, may subvert a less comprehensive list. I believe another advantage of the "being" side is that it is more positive and thus more appealing.
If I want to be a successful executive, bricklayer or parent, the ultimate goal will not be attained immediately and yet playing the role of one who will eventually achieve it can be assumed instantly.
By doing, we become. By being, we do.
