My favorite working years were in the '80’s when I worked evenings (4pm - 12:30am). I was in my 20’s. I took classes, taekwondo, easily scheduled any appointments, went to the store when it was less busy, etc. I’d get home before 1:00 am, relax for 30-45 minutes and go to bed, then awaken naturally in the mid-morning, no alarm clock needed! I’ve always been a night owl so it was the perfect schedule for me. I’ve also worked overnight shift which was the worst, not good for sleeping (during the day when it’s bright light and hot and people making lots of noise).
