Stop aging. No, seriously, stop aging. You're the perfect age right now. It doesn't get any better than 18.
It's not that people can't tell you what to do now that you're an adult, it's that you have to pay the full consequences of your decisions. Enjoy not having to listen to anyone.
Now that you are 18, don't expect to ever be trusted by kids again.

Don't get too big of a head about your age. You're still a teenager.

16 is about growing up and becoming independent by driving. 18 is about being responsible and being treated like an adult. And 21 is about being just old enough that you probably won’t start drinking if you haven’t already started. Remember that you are now responsible for your own actions, but the government still doesn’t trust you with alcohol.
Alice Cooper wrote a song about you, and I think you are just now old enough to listen to it. Enjoy my recommendation.
It’s scary that they let 16-year-olds operate a motor vehicle. It’s scary that they let you vote at 18, but it’s even scarier when you turn 21. Then they let you carry a hand gun and drink. It get’s scarier and scarier watching you grow up.
Enjoy your rights as an adult while you still are reckless and energetic enough to get the most out of your new privileges.

Even though you’re technically old enough to operate military equipment worth millions, be tried as an adult as a criminal, sign legal documents, and kill yourself with cigarettes, you’ll have to wait a few more years before they’ll let you decide to do these things under the influence of alcohol. Thank goodness you are only 18.
Some things in life are worth waiting for, like all the things you can do now that you're 18.
