I've spoken out against ambition before, but it's not entirely obvious what I mean: it's not that I think that people shouldn't have goals and things, but there is a time when people switch to using the people and systems around them instrumentally instead of relationally, and that's the ambition that's so damaging. At work, we call it 'workplace politics'. Sometimes playing the games yields a net benefit, but the earth is salted for community when it happens.
You fundamentally cannot grow community without the humility to let things go at their pace, in the collective direction. It's the mentality of stewardship, or of the gardener or horticulturist. Even at its most controlling, stewardship works within, not without. You can sometimes steer, you can guide, but in the end you have little control but pruning here and there and fertilizing where needed.
