You wrestle one night, get up the next morning and fly out to the next city. You try to work out, you try to get some food into you and, lo and behold, you have to go work again. You are living out of a suitcase. ↗
I try not to be too optimistic or pessimistic. If you're a pessimist then that's depressing all the time; if you're an optimist and things don't work out then that's depressing, too. ↗
