Personally, I don't think it's that big of a deal to live on your own. I live on my own right now for med school, and go home every weekend and my parents call me every day, and really wish I just lived with my parents at home. Seriously, because really wherever you are, there's really no place like home.
Things, like hooking up a cable, and getting internet, you only need half a brain to learn how to do these things. As for cooking, heck! My mom and all the aunties I know never lived on there own, and they cook the best food ever!!!! AND KNOW HOW TO SEW!!
So for all of you living at home with your parents: I say you have it great!! It's not like you can be with your parents forever, so really I envy all of you!
