When I say it makes sense to borrow money when you’re young, I’m not saying you should be racking up credit card debt—such high-interest loans are a bad idea for almost everyone. Borrow modestly and responsibly. And when you have many years of rising income ahead of you, it really doesn’t make sense to save 20 percent of your income. That would mean forgoing memorable life experiences you could be having, and it also means working to pay for a richer future self—a suboptimal use of your life energy, that’s for sure.
