Alex Honnold is without a doubt the world’s best solo climber and in this TED Talk he shares with us his story of how he climbed Yosemite’s El Capitan and lived to tell about it. Alex shares some pearls of wisdom during his talk that can help anyone overcome something they are afraid of doing. For me, the best lesson from his talk is how much planning and practice he did before he attempted what in all regards is an impossible climb.
