The lemons problem refers to the difficulty in assessing the quality of a product when the seller has more information than the buyer.
“柠檬问题”指的是当卖家比买家掌握更多信息时，评估产品质量的困难。
译文：认识到过去所做的事是错误的，那么说明学问在日渐进步；能看到别人的言行有可取之处，说明德行操守在日渐提高。赏析：一个人的思想若要变得成熟，肯定要读书学习，更要学习别人的长处和优点。人愚昧无知不可怕，最怕愚昧无知还不自知，还不懂得学习和改变。
Never say never, because limits are just illusions.
"The act of creation is a rebellion against the void."
