"どうやったらお金持ちになれるか教えます。ドアを閉めてください。他人が欲深くなっているときは恐れ、他人が恐れているときは貪欲になりましょう。"

Simplified Meaning:

The quote advises a smart way to approach opportunities, especially in business and investing. When most people are eager and rushing into something because they think it's a great deal, it's often a good idea to be careful and not follow the crowd blindly. This is because when everyone is buying, prices go up and the opportunity might not be as good as it seems. On the other hand, when everyone is scared and avoiding something, that might be the best time to invest or take the opportunity. For example, during an economic downturn, stocks often drop in value because people are afraid of losing money. If you're brave enough to buy then, you might get stocks at a low price and make a profit later when things get better. In everyday life, this could mean taking a step back and thinking twice before jumping on trendy bandwagons or avoiding something just because others are scared. By being thoughtful and strategic about when to act, rather than following what everyone else is doing, you can make better, more profitable decisions.
