All excellent advice. I am three years into retirement. Year 1 was fantastic for me, I was still riding the wave and it felt like a really long vacation, I was still connected to my old job and mentoring my successor, but all that changed in year 2 and I felt I had crashed into my lowest point mostly because I was really missing my old life and career which were intrinsically intertwined...toward the end of 2022, I slowly emerged out of the trough and started to put some distance between the old life and the new. I still miss many aspects of my old life but the new things on my to-do list are taking more of my time and energy and giving me a lot of satisfaction, so it looks like I am finally on the way to a more rewarding retirement.
