In my own case, I love my night sleep a lot because that’s the most quiet time to have a good rest without any noise but like you mentioned career choices I made earlier now keep me awake in the mid night doing nothing, I’ve to force myself to sleep especially on weekdays.

Another one that interrupts my sleep most time, is the need to use the rest room at night. I hate it when I’ve to pee.. I try to keep my eyes close when I walk down to the rest room, hoping the “sleep” doesn’t escape 😂😂
