The issues outlined in this essay are why, as an organization, it's important that if you want your members to be ambitious, you need to be positive, cooperative, constructive, and helpful.

I don't mean "don't provide any critical feedback" or "competition is bad", I mean, the point of you having an organization is to have a group with some goal, and if you want to accomplish that, you should cooperate. If you're going to provide critical feedback, do it with the aim of improving things, not just to tear things apart.
