About “而浮生若梦，为欢几何？”

This line originates from a Chinese poem by the Tang dynasty poet Li Bai, which I hold in great affection. It translates to the English sentiment as ‘Our floating life is like a dream; how often one can enjoy oneself?’ The poet intended to convey through this line that human life is ephemeral, akin to a fleeting illusion, urging us to embrace each day with a carefree attitude.
