This. OP described his duties as 12 hour shifts. This guy was a fobbit. Now there are fobbits who work their ass off and do great, important work. I loved them. I was one once. None of them describe their work as a 12-hour shift. OP also quickly put his service in the context of marking time until his commitment was complete. "Just when I thought I was out... they pulled me back in!"
Thanks for your service. And a sincere !Congratulations! on your success. But the title is link-bait which exploits the experience of those who had it much tougher than you. Stay in your lane.
