My wife and I aren't in any of the high risk categories so not too worried about ourselves, but don't want to be part of the problem by getting it and spreading it. I'm paying a lot more attention to washing my hands, avoiding holding handrails on stairs, etc. and with all the major events being canceled there isn't much reason to be out in crowds right now. Also, I already work from home so no change necessary there.
What I am worried about, though, is that with all the panic buying going on and people wiping out grocery stores, that is going to cause severe difficulty getting necessities if you haven't already stocked up -- which creates more angst about stockpiling and therefore continues the cycle. The grocery stores here are not able to keep up and it sounds like they may be forced to temporarily shut their doors if only to catch up on distribution and stocking. I'm not so worried about toilet paper because there are other ways to clean yourself, but the shelves here are devoid of canned food, fresh meat, etc. so it's getting to the point where you can't get food at all, let alone enough to stockpile. I am starting to see stores rationing these items so that individual customers can't wipe them out but they still have lines outside before they open in the morning. We're trying to opportunistically grab a couple extra of some of these items when we are grocery shopping but not going crazy -- there are only 2 of us, we shouldn't need that ridiculously much to survive for a couple of weeks.
tl;dr: We're buying a little extra to stock our pantry when we shop, working from home, and washing our hands more often and more carefully.
