📖 Meaning
To take great delight in something and never grow tired of it. It describes a deep passion for a particular activity, where one is so absorbed that weariness never sets in.
📜 Origin Story
The phrase originates from the Book of Later Han (后汉书), in the Records of Emperor Guangwu. Emperor Guangwu (Liu Xiu, founder of the Eastern Han dynasty) devoted himself tirelessly to governing the realm, and when reminded that he should rest, he reportedly replied, 'I myself delight in this and do not feel weary.' The saying later became an idiom expressing wholehearted, unflagging devotion to a pursuit one loves.
