I just wish everyone would check their ego at the door

Runs don't need to be perfect. But it's also not asking much that you are properly geared and know the things you so you know.

If things are going well, don't start shit.

If someone's clearly struggling and someone needs to say shit don't be an ass. And person being criticized, don't escalate or get overly defensive.

Shit ain't hard. Just requires viewing the others on your team as human beings who are flawed but entitled to their time being respected.
