I loved shift work during ns. night shift essentially you can do your own thing (study, read newspaper, talk cock sing song with unit mates, watch ancient 90s reruns on tv, even play app games - this never existed in my time) and enjoy the quietness of the night. best part is you get the full day off the following day. Not that bad assuming you don't have any siao on specs or officers assigned for duty on that night.
The days will fly pass when you do shift work and before you know it time to ord already.
