In one of my college classes, a professor named Sandy Zensen emphasized two points. His first point was that we should invest our lives in people. That is what Jesus did, and we would do well to follow his example.
His second point is captured in this statement: “I am not afraid of failure, but I am afraid of succeeding at something that doesn’t really matter.” I agree with that sentiment. Our greatest fear should not be of failure. Our greatest fear should be of being successful at the wrong thing.
