Selfishness is like a disease that suffocates our capacity to love. While love asks us to deny ourselves for the sake of another, selfishness demands we put ourselves first at their expense. When we choose to be self-centered, we become less kind and content—more needy, sensitive, and demanding. More unsatisfiable. Moodiness and impatience, laziness and irresponsibility, are only selfishness in disguise.
