Easier said than done for those of us who don't have pension, SS and so on. At least my house is paid off.
I put what I thought was way too much in cash when I retired in order to get us to SS time. It is coming in handy, and is kind of fun to buy my T-Bill of the week.
When we both retired in '18, I expected a 30% drop in market and felt we could handle a 50% drop. What I didn't see coming was a moribund bond market (as part of 401k index funds) and raging inflation.
Still think we can handle it, and look forward to SS going up with inflation, but man, this is a test.
