I think those plug extension things have safety features now, so you can fill all the plugs. Just don't, like, start a chain of them.. I think that's when problems might start.
Hmmm...
Keep things clean, (especially bathroom, dishes, fridge, desk area..) take out the trash, vacuum, (get a GOOD vacuum, cheap ones won't work and will break soon) clean up spills right away. Otherwise you can get mold and bugs and bacteria and stuff, and the air becomes unhealthy to breathe. And watch out for fruit flies in Summer. If they start to gather, find what's attracting them and do something about it or they'll start to breed there.
Open windows regularly for good ventilation and to keep moisture from... moistening your room. Also prevents mold.
Eat vegetables.
Try not to lock yourself out.
Uuuuh....
I dunno. It's really not that hard to survive. I was surprised. It was basically the same as living at home, except I had to start doing my own cleaning. It's easiest to do if you just clean a bit here and there every day as you go about your business.
