The underlying fact is, each editor chooses his level of activity. His RANGE of activity is self-selected (subject to approval from meta-editors).
The appropriate way of dealing with that fact is: start small, and work up. If you're interested in a global health category, the logical first step is a local health category. Because, once you've established a reputation as an effective editor in smaller categories, the community will be eager to have your help on larger categories.
The "bwa-ha-ha" stage is not obligatory. There are other possible role models, and it's not obligatory that you choose a role model. I would suggest, though, that very few editors you WOULD want as a role model would, in their first introduction to a new community describe themselves as either "humble" or "honest", let alone "simple". That is, I grant, a subtle point -- if hardly a new one (Proverbs of Solomon, 27:2).
