The freedom is pretty cool, you don't have anyone telling you what to do or anyone bothering you about anything. It's good to know how to cook so you don't have to eat fast food for almost a year like I did. If you don't know how to cook just try it, it's actually pretty easy after a few mistakes are made.
At first I used to clean my room every day, but as time went on and I became loaded with work I started doing it less and less. I'm a master at messing stuff up, so if I clean up and order my room it's probably a mess by the next day XD. I still try to clean as much as possible though.
Just don't worry about it, I was kinda nervous when I decided to move out, and it was kinda hard at first figuring out everything. But you quickly get the hang of it and realize it's awesome living on your own.
