弱水三千只取一瓢饮
[ruò shuĭ sān qiān zhĭ qŭ yī piáo yĭn]
An expression often quoted from Chinese literature and ancient poetry. It literally means there are countless rivers, symbolizing many available options (such as lovers, friends, pursuits), yet one only chooses the most essential part of what really matters—expressing monogamy in romantic relationships, focusing on true values or simplicity despite plenty distractions.
