On the endless beach, some people collect many shells and return home with a full load, while others prefer to be a drop in the ocean in search of perfection in their hearts. Just because the watchfulness in the heart lasts forever, one can only pursue it recklessly and persistently. "No matter how the world changes, no matter how the form changes, the inner yearning will never change," said Michael Haneke. A person with a watchful heart is like a stove with a fire, with a burning heart, firmly rooting the roots of the soul in the heart. Watchfulness lasts forever in the heart, so that silence will not be shrouded in every corner of the era, and noble sentiments will remain in the great heart forever.
