same here, until I closed our startup ~6 months ago and decided to do nothing after 19 years of working hard and pushing upwards. I lived with my partner so I wasn't paying rent, and now I changed my mind about retiring - I can't wait. I still got to dabble, I helped a founder friend with her core tech, I visited friends, played a bunch of video games, spent more time with my partner, and I loved it. Time felt comfy, I purposefully was not looking for work, my stress levels went down, I walked my dog at least an hour a day. I'm now going back to work, even harder problems and responsibilities, and while I'm likely to enjoy that, I am now looking forward to when I don't have to (assuming that happens)
I wrapped this up a while ago, but sharing because a few friends found it useful.
