It is also very easy to talk about all of this in hindsight.

Prior to April 2020 I had 100% of my 401K in cash/equivalents.

In April 2020 I put half of that cash into stocks.

Now, of course, I kick myself and say I should have put most/all of it into stocks back then.

But that kind of "of course!" and "that was such a recognizable pattern!" talk is a lot easier in hindsight.

It's easy to forget what it was like at the time, and that it could have easily gone down even further. At the time, the cat was both dead and alive (market recovers vs. market falls further).
