A fool and his money are soon parted. — Thomas Tusser

A fool and his money are soon parted.

Insight: We like to think we're smarter than the people who fall for obvious traps. But this old saying captures something more subtle than just gullibility. It's about how confidence and carelessness are more dangerous to your wallet than actual stupidity. Smart people get parted from their money all the time—not because they're dumb, but because they're too sure of themselves, too distracted, or they want something badly enough to ignore the warning signs. The real insight is that financial mistakes usually come from emotion, not intellect. You overspend when you're sad. You make a hasty investment because everyone else is doing it. You ignore the fine print because you trust someone. These aren't failures of intelligence; they're failures of attention and discipline. The best defense isn't being clever—it's being boring about money. It's asking the basic questions everyone skips. It's moving slowly when others rush. What makes this saying endure is that it's not actually insulting you. It's reminding you that regardless of how sharp you are in other areas, money has its own logic. And that logic is simpler than you think: know where it's going, question the deal that seems too good, and remember that wanting something doesn't make it a good idea.
