How can growing up be both exciting and painful?

Growing up can be exciting because, when you are young you want to be able to do what you want to do when you want to do it. You see grown ups driving, partying, and alot of other stuff and don't have to ask their parents. Growing up can be painful because when you are grown you have to deal with bills, car notes, and a bunch of other difficult stuff. Plus you have to pay taxes!
