Unfortunately, I'm not so smart, so I just stopped checking the quotes for my portfolio for a while (except for the stocks that I wanted to sell anyway). I knew that I was down, probably by a lot, but only a couple of months later I found out that my portfolio was down by a whopping 40%+ YTD by mid-March. However, there was no point to look at it back then. It was kind of obvious (I've checked my notes from the time) that barring a nuclear war scenario the value was still there, either in terms of long term cash flows or balance sheet or whatever you do to value stocks. So assuming that stocks are not just pieces of toilet paper circulating in an outlandish global casino but represent a stake in some business there was no point to self-torture by way of constantly refreshing panicky mark-to-market prints of my portfolio holdings.
As for the kids, we hired a nanny for a few months. It cost us a small fortune, but eventually, it was worth every single euro cent. Neurons are not compounding, unlike investments.
