What to do in able to move out of parents' house?

The first thing when moving out is just consider your cost of living. You'll need to realize that your money is no longer fun money and has to be properly allocated to paying bills, and hopefully having some left over to set aside for a rainy day. Other than that it's all pretty much common sense as (not that that bit isn't, but it seems most people just straight up can't do that).

Yeah, I'm actually super-aware of that right now, actually. In terms of clothing, if I need some, I guess I'll just go to Marshall's or some place that sells used clothing. I'd rather stay away from the mall because sh`it there isn't always great quality, and not only that, but sh`it are always logo'd to death (ie: American Eagle, Abercrombie, Aero, etc). Clothing in malls are also super expensive too, so.. yeah.

In terms of food, I will have to buy groceries and cook for myself since it's cheaper that way (in comparison to buying 1 dollar frozen entrees). I've been buying groceries since I was little though, so I know what to shop for, and I can cook. So I can fend for myself rather well in terms of cooking, but I am actually worried about things such as a mattress. I might just buy an inflatable mattress. Or just spread out a sheet and sleep on the floor.

I envy you.
I think it might be too early to start wondering about details.
Looking for places to live, prices and whatnot... it's really early, unless you just want an estimate.
If that's the case I'd look up decent places to live and their prices, food&services prices, gas and whatnot. Add "few" bucks to each thing because things get pricier every year.
Then I'd think about the jobs I might be able to get and if they can pay for my survival.
The only thing I'd advice you is to start saving as much as possible from now on. If there are any emergencies, when living on your own, it would be great to have few saved bucks.

Actually, about that. I actually have a couple hundred bucks on only ONE of my credit cards that I need to pay back, once I work full-time this Summer and pay back everything, I think I'm going to learn how to conserve money as I go to school for the following Fall semester. I'll keep track to see how much money I spend a day, up to a week, up to a month, etc. From there, I can estimate to see if I can live by myself. But like I said, I won't be able to move out anyways since I want a stable job. I am of course, also going to be saving money after this Summer. I'm also going to be taking 15 credits, instead of only 12 (as usual ; as I normally do). I want to speed this up so I can get out fast.

My goal to keep up that motivation would be: "I will be able to get the f`uck out of here if I finish school fast."
