1) I have not missed work at all for the last three years. Not a single day. I have not done any programming since I retired. Instead I spend my time on other hobbies and travelling. I try to take two week-long trips every month to new locations. That is plenty meaningful for me. I have nothing to prove, I already did that. My job now is to see the world while I still can.

2) Initially it was daunting to start living on savings / investments. Especially with an initial ~20% market correction and high inflation. However I am spending less than I expected, only around 2% withdrawal rate and I could reduce that by almost 50% if needed and still live rather comfortably.

3) Financial independence is nice. But you also have to spend the money, while you still can.
