How can growing up be both exciting and painful?

Growing up can be exciting because you are finally independent. You can finally do things on your own. There is no longer a need to be supervised. You can make your own money and buy your own things. Growing up can also be painful because making your own money comes with responsibility. Like helping your parents with the bills. Going to work every day and actually doing your work. You can no longer depend on anyone but yourself . you cant just spend all your money on clothes and things like that. You have to save for emergencies.
