This is what I would call a muscular humility—a mindset of seeking simple ways to serve the group. Picking up trash is one example, but the same kinds of behaviors exist around allocating parking places (egalitarian, with no special spots reserved for leaders), picking up checks at meals (the leaders do it every time), and providing for equity in salaries, particularly for start-ups. These actions are powerful not just because they are moral or generous but also because they send a larger signal: We are all in this together.
