Nik Wallenda is an American follower of Christ who has become the most-watched high wire artist and daredevil in the world. His two most recent feats were seen by a billion people across the world. In 2012 Wallenda walked a tightrope across Niagara Falls. In 2013 Wallenda became the first person to high-wire walk across the Grand Canyon.

Wallenda knows that he will be tempted by pride, so after the huge crowds and the media fade away he engages in a simple spiritual discipline: he walks where the crowds have just stood and quietly picks up trash. Wallenda recently wrote,

My purpose is simply to help clean up after myself. The huge crowd left a great deal of trash behind, and I feel compelled to pitch in. Besides, after the inordinate amount of attention I sought and received, I need to keep myself grounded. Three hours of cleaning up debris is good for my soul. Humility does not come naturally to me. So if I have to force myself into situations that are humbling, so be it …. I know that I need to get down on my hands and knees like everyone else. I do it because it's a way to keep from tripping. As a follower of Jesus, I see him washing the feet of others. I do it because if I don't serve others I'll be serving nothing but my ego.
