Meaning: This quote give us a message that we should work to seek respect, not attention as respect is eternal, and attention is temporary. For example if we look around or at history we will find that we remember those people whom we respect, and we respect those who speak softly, help others, and respect others or who has done something for our society and not those who do not helped others and just worked to seek attention like by owning luxury cars or houses.
