Don't pursue happiness; create it.
Ben and his two young sons were one of many families on this wagon train. After Inger's death, he had decided to continue to pursue his dream of heading west where he thought happiness lived.
One of the downfalls of being on the trail was one had plenty of time to wrestle with one's thoughts. Ben glanced over at Adam sitting next to him in the wagon and observed baby Hoss sleeping soundly in the back. It was then that he realized happiness wasn't something he needed to chase. Happiness was here and now in his family that he created.
