"Once a man worries, he clings to anything out of desperation; and once he clings he is bound to get exhausted or to exhuast whomever or whatever he is clinging to. A warrior-hunter, on the other hand, knows he will lure game into his traps over and over again, so he doesn't worry. To worry is to become accessible, unwittingly accessible." - Don Juan, from Carlos Castaneda's "Journey to Ixtlan."
