1) Layer up, and layer up with good, clean layers. %100 wool socks aren't necessary, a blend is great. Also, make sure that you're not SO layered up that the layers are squished together - that just squeezes out the air and lowers the effectiveness of the insulation.
2) if you're going to go outside for a strenuous activity or for any length of time - dress to be "comfortably cold." Don't wear so much that you're comfortable when sitting around indefinitely - because when it comes time to exercise you'll start sweating - even if you don't get heat stroke (which - YES - it CAN happen if you wear too much in the cold), you'll sweat all over your clothes and when you cool back down again and risk getting hypothermia if you can't get into some warmth. Instead - your best bet is to dress such that at rest you'll be on the cold side. Mind you - this is basically applicable only if you're doing some strenuous work or spending multiple days outside.
3) Hydration STILL matters. Keep drinking water, hot drinks and soup are great for this kind of weather. Also chili (chilli?).
4) If you have window sills, you can put your beer and beverages on the window sills outside of your windows, and then grab them when you need a new drink. It's great for house parties. You're welcome.
5) If you have to drive anywhere, 4-wheel drive has a BIG advantage in the snow. if you've got it, maybe ask your neighbours that don't if they need any groceries. Also, go slow and stop well before you think you might have to. You can slip and slide even WITH winter tires.
6) Bonhomme de Neige - or the good snow man, may look creepy but he just wants to hang out. At the end of the day - "making it through" any situation is about your mentality, so be like Bonhomme - he loves it out there. You've got this, it's the perfect temperature outside for your beer or your rum and coke, so get a few guys together with a case of beers and some shovels and go through the block shovelling the driveways of those who can't (the elderly, the disabled). Smoke if you got 'em, make some barbecue, make a snow man with your kids, then go indoors for some hot chocolate. Take pictures. It can't be a bad time if you get to help your neighbours while having a good time with your friends.
