Odds of Hanging On
Anyone can get a degree in supply chain management or industrial engineering (okay, maybe not anyone) but it's going to take a whole lot more than that to actually excel in this line of work. Aspiring logisticians hoping to climb the ladder should be absolute aces at critical thinking and problem solving.
Everyone thinks they're good at those things, but it's important to be honest with yourself now so you're not sitting around confused by your lack of promotions after twenty some-odd years at the same desk.
While you're thinking about that one, take a good look around. Do your things appear neat and tidy, or like a hurricane blew through? Incredible organizational skills are paramount in the field of logistics and people without them probably won't last a year, let alone a lifetime. So go on. Get a start on it now and clean that desk. We'll still be here when you finish.
