When you’re just starting out managing your own finances, little things like paying your own bills, going to the bank, and even grocery shopping “like an adult” can feel empowering. But if you’re reckless and don’t pay attention to money management basics???or just don’t know any better???this is also when you can make the biggest money mistakes of your life. Take it from me, little grasshopper: One of the reasons I have such an interest in personal finance now is that I’ve broken just about every personal finance rule there is???not purposefully or knowingly, but just in the course of being young, foolish, and learning to manage money on my own. If you’re reading this now, you’re probably wiser than I was at the time, but hopefully you can still profit from my experience.
