[GH] Stay for the pay or jump for a real challenge after NSS?”

I’m a first-class petroleum engineering graduate doing my NSS in operations at an oil terminal. When BRV traffic is low, there’s basically nothing to do, and the job feels too slow. After NSS the pay is around 4–4.5k in the first year and 5k+ in the second. I’m not sure if I should stay or look for something better—maybe something more upstream or technically challenging. For someone in my position, what’s the smarter move after NSS?
