Have you ever looked at your finances and thought, "I should know this by now" ? If so, you're not alone. I've met countless "intelligent" people who feel uncertain about money, not because they aren't smart, but because no one ever taught them a clear way to think about money. There's no shortage of financial advice. What's often missing is understanding. Understanding is what builds confidence. Looking back, what's one thing you wish someone had explained to you much earlier about money?
