Go On and Take a Bow
I am treating today as a victory lap. We got through testing last weekend, hit all our performance metrics, identified and corrected a major system setup issue, and filed a defect (bug report) for the only problem not ours to fix.
Filing a defect is like punting a gigantic turd. It still stinks, and now some of it is stuck to you, but at least you don’t have the turd anymore.
