Think of stress, however, as occurring on a continuum (it does). Below the “stressed out” level of distress is the useful level of stress called eustress. It's pronounced “you-stress,” and that eu- prefix is like the prefixes on euphoria, euphony, and eudaimonia. Eustress is the stress you feel that helps you get ready, get excited, and “get up” for the big game. It's that tingly feeling of anticipation, eagerness, and a sense of fire and determination that you feel when your team huddles and shouts, “Team!” or, “Beat Navy!” before a game.
