The document describes two experiences the author had overcoming obstacles during outdoor adventures - crossing a deep river in a small car to reach a hiking trail, and finding no safe river crossings while hiking in the Sierras so stripping down to underwear to walk across carrying packs. The author says both experiences taught the same lesson - that having a goal and facing obstacles requires powering through rather than turning back, and this principle can be applied to achieving life goals by being willing to do whatever it takes through action and feedback rather than giving up at the first obstacle.
