So you've turned 18, you own a car, and you're ready to move out of your parents' house. You might feel like you're all grown up, but in reality, your journey toward adulthood is just beginning. You'll soon be faced with lots of formative decisions, including where (or if) you should go to college, how you're going to spend the money you earn, and, eventually, whether or not you want to get married and start a family.

Most of these choices come with a hidden financial cost, but if you know what they are, you'll be much more prepared to make confident judgments about the future. That's why Entrepreneur recently published the infographic below, courtesy of education software company PathSource. If you can answer some of the questions it asks, congratulations—you're officially on your way to becoming a real adult.
