Literature Reference: 穷通谅在天，忧喜即由己。是故达道人，去彼而取此。勿言未富贵，久忝居禄仕。借问宗族间，几人拖金紫。勿忧渐衰老，且喜加年纪。试数班行中，几人及暮齿。朝飧不过饱，五鼎徒为尔。夕寝止求安，一衾而已矣。此外皆长物，于我云相似。有子不留金，何况兼无子。——《把酒》白居易 Poverty or prosperity lies in heaven, while worries and joys are up to oneself. Therefore, the wise discard the former and embrace the latter. Do not fret about wealth or status, for longevity and contentment are true blessings. A simple meal and a warm bed are enough; all else is superfluous. One who has no children need not hoard gold. Source from 'Wine' by Bai Juyi.
