Stick with it. I did the ramp/flightline for years. One of the best ways to get started in this career and in my opinion probably the most rewarding.. You can trully say that you have been in everyones shoes involved with the operation. From tasting glycol during deiciing in a blowing snow storm to getting dumped on from a failed dougnut plug on a lav service or handling angry pax for what ever reason..I've done it. Flying a heavy now and on long flights when I reflect upon the past, I will smile knowing that I trully have made it to the top from the very bottom.
Also the ones that have been there will back me up on this... doing the commuter/turboprop thing, 8hrs/day 8-10 legs a day, no autopilot or moving map or efis... to challenging destinations with unpredictable wx.. Sets a foundation for your career that is unparalleled.
P.S.
We use to walk to work uphill in 3ft of snow also
Best of Luck
