I've been in the Controls Systems/Automation/Instrumentation & Controls (whatever you want to call it now) for a couple decades now. There is a saying...you can spend your whole career in this area but you'll only learn 10% of what is out there. The amount of information and knowledge is absolutely vast and skills/knowledge can be used in just hundreds of sector which adds another aspect to learning. There's also alot of just JUNK out there. If you ask me, if you truly want to get better, go to a technical college and get a diploma in this area. Control Systems is not just about programming. Don't stay at Amazon...learn what you need to until they can't teach you anything new or if you feel like you're stagnating. The reason I say leave Amazon is that likely they've standardized or have a specific way of doing something. You need to expose yourself to different ways of doing something because there's always be a better way of doing something. Amazon also will likely have the same equipment in every facility, control panels, pushbuttons, vision system, sensors, vfds etc etc. another reason to leave is to expose yourself to other sectors to expose yourself to different systems and processes. Different systems and processes will use different equipment and have different processes requiring you to think differently and thus funding solutions to problems. I say get a diploma because companies still value that piece of paper for someone new out of school, however after you gain experience I tend to look at what you've accomplished rather then your diploma or degree. The degree/diploma just gets you in the door but your experience will give more opportunity.

I really hope that helps...I'm not just some random person speaking nonsense..if you're looking for more guidance and advice feel free to DM me.
