Welcome to ER from another ISTJ. I had to "come out of the shell" to work 29 years in law enforcement but a lot of people had that issue.
DW and I are still enjoying having all the free time we want. She loves having all the time she wants to deal with helping family with some things that take a lot of time. I'm going back to work to buy toys, like maybe a travel trailer.
I heard the call to do nothing. So I answered it.
