Gazing at Plums to Quench Thirst
曹操行军士兵渴极，说前方有梅林，士卒想象酸味而生津，得以坚持。成语指用想象暂解当下之难，也喻空想安慰。
Cao Cao tells thirsty troops of plum forests ahead; imagined sourness brings saliva and they push on. Idiom: temporary relief by imagination—also a warning about empty comfort.
愿景可短时提振；但不能替代真实的水源。
Vision can boost briefly; it does not replace real water.
After the moral, ask one question: if a similar choice showed up today, where does the story snag? Name that tension first—then take your own step. You need not copy the ancients, only borrow their clarity.
