The top 10% are like the Heat. They accept responsibility, regroup, refocus, and come back charging. They hit the court / office, make note of what didn't work and what did, and leverage their strengths. Sure, take a breather after a big loss. Step away from your desk. Go for a walk, lunch, or take an afternoon at the park. But, while you are away accept that YOU lost the deal and only YOU can stage a comeback. Comebacks start only when you take responsibility and then take action.
