Teen,
I know the freedom sounds glamorous. Making all your own decisions! Let me give you a little life lesson.
So you leave your parents house and now you need a job to support yourself and a place to live. Who is going to rent you an apartment? You (presumably) dont have first and last months rent PLUS security up front. OK so you find someone nice and they let you move into a tiny basement apartment. But, there are rules there too (like no painting the walls or no loud music etc). So, restrictions.
Then you look for a job – as a high school graduate (or not even that), what do you qualify for? Flipping burgers at McDonalds? And with this economy, you are competing wtih College Grads for that job. But ok, you get the job. Now, your boss wants you there at 7 am sharp – no excuses. You need to tuck your shirt in – no excuses. You need to wear these ugly uniforms and always make sure to say yes maam/sir. And if you forget to give a customer a reciept, they get the meal free and it comes out of YOUR salary. So, more restrictions.
There is no such thing as a life without restrictions. In the realworld, there is always a boss telling you what to do. At least with Judaism, there is a clear guide to the rules :-/
