That's pretty much what I'm doing. Make sure I'm fully stocked on non-perishable essentials (that I'll actually use); make sure my emergency fund is topped up; make sure my home is in decent shape.
There's no point trying to play the markets (as in: guessing when to switch from more aggressive to more conservative funds). Though I am hoping to scrape together a bit of spare cash to try to buy a bit when I think some stocks or mutual funds are at a low. But I doubt I'll get a chance to do that.
I'm not as worried about a huge recession as I am about the prospect of massive political/social turmoil. To me that's the true chaos factor.
