"What the hell am I doing?" Sooner or later most of us ask that same question, writes J.D. Tuccille. We ask it when we're doing something foolish, or brave, or unfamiliar, and we especially ask it when the situation goes sour—when we find ourselves airborne in late-morning traffic. And if we don't ask it of ourselves, somebody else is sure to do us the favor: "What the hell are you doing?" But it's important to remember that while everybody has the right to ask the question of himself and others, only the person on the spot, the person living that moment has the right to decide whether the answer is justifiable.
