Never start running

He had come to New Mexico wanting no trouble. He had wanted no trouble at Horse Springs, and wanted none on North Plain, but long ago he had discovered that one has to make a stand. If a man starts to run, there is nothing to do but keep running. And if a man must die, he could at least die proud of his manhood. It was better to live one day as a lion, than a dozen years as a sheep.
