The key is to save as much as you can, as early as you can.

Insight: Most people know they should save money, but knowing and doing are miles apart. The real power in this advice isn't just that saving matters—it's the timing part. When you're young and earning less, saving feels hardest. Your salary is small, your expenses feel large, and retirement is an abstraction decades away. But that's exactly when it counts most. Money saved at twenty-five has decades to compound and grow into something substantial, while money saved at forty-five has far less runway. The tricky part is that early saving requires a kind of faith. You're being asked to sacrifice something real now—that weekend trip, the nicer apartment, the newer car—for something theoretical later. Your brain isn't wired to feel excited about compound interest. Yet the math is relentless. Even modest amounts matter enormously when they have time to work. It's like planting trees: the best time was years ago, but the second-best time is today. What makes this harder now is lifestyle inflation. As you earn more, your spending tends to rise too. The discipline isn't just about putting money aside; it's about catching yourself before your expenses automatically expand to match your income. That's where the real victory happens.
