“Life is not about one obstacle, but many. What’s required of us is not some shortsighted focus on a single facet of a problem, but simply a determination that we will get to where we need to go, somehow, someway, and nothing will stop us. We will overcome every obstacle—and there will be many in life—until we get there. Persistence is an action. Perseverance is a matter of will. One is energy. The other, endurance.”
