Many people enjoy the refreshing feeling of a house after a thorough cleaning. Similarly, there is a sense of beauty in getting a haircut, as the excess is removed, leaving one feeling light and renewed.
Children are inherently happy because they carry no heavy burdens or unnecessary worries. Adults, however, are different; our lives are often cluttered with accumulated baggage, imagined complexities, and amplified sorrows.
Those who use computers know that the recycle bin must be emptied regularly; otherwise, it consumes excessive space and slows down the system. The human mind works the same way. You cannot discard everything, nor can you keep everything. Wise people excel at making timely choices Between what to keep and what to let go. Those burdened by too many thoughts struggle to move forward, while those with no thoughts at all often lack rationality.
This is precisely where the difficulty of life lies: you must constantly sweep away and relinquish certain things, for "the less stuff that fills a life, the more potential one can realize." I recall a scene in a movie where someone told the protagonist, "Go, don't look back, and don't come back if you fail." The intent was for him to move on completely, ensuring the past did not become a weight holding him back.
Clearing the soul is a process of struggle and striving. Life is a journey of continuous farewells: youth must bid farewell to their hometown, the heartbroken must leave the places of their sorrow, eagles must leave their comfort zones, and joy must sometimes bid farewell to sadness. Without farewells, there is no growth. To be strong, one must find the courage to turn away, understanding that parting is often for the sake of a better reunion.
