It’s not the morality of it that I speak of. The main issue is that in our preoccupation with ourselves, our vision narrows, our growth is limited, and our failures are amplified. Curiosity and excitement for challenges gets replaced by anxiety and fear of failure. The potential for self-rejection grows.
