1. Stock up on booze and food, and more booze
This is crucial, people. If you're planning on hiding in your apartment all weekend, then you'd better make sure you've got plenty of booze to help keep you warm and, well, sane. Now's probably a good time to invest in a decent bottle of whiskey or maybe a couple of those cheap oversized bottles of red wine -- or whatever's going to help make spending the day in your precious little space suck less. Being prepared means rolling out of bed and sipping a mimosa while the first flakes fly.
Stocking up on food, too, is critically important, unless you're a monster and plan on having delivery people trudge through the ice and blowing snow to bring you pizza and General Tso's Chicken (in which case, you'd better tip well). But if you want to enjoy things like bananas, fresh-made pizza dough, or even a flake of kale this weekend, now's the time to get off your ass and get to the grocery store... before Trader Joe's devolves into an at-capacity basket-kicking bloodbath, like last year. Easy essentials like frozen pizza, sandwiches, and pre-made foods that require little to no cooking are recommended. Bottled water is probably another safe bet. Oh, and don't forget pet food, if you need it. Especially if you have pets.
