Hmmm I think it's important to realize that everyone begins at the same place, and travels on a path... are we all on the same path? No.. not all... but similar paths. No one is better than another, just as a different place on their path. Perhaps to investigate what is causing you to feel "low blows" might help you to not become frustrated in the future, I don't know. For me, intelligent discussion and tough calls in good judgment are not mutually exclusive.
