I came in via the support track, my advice would be to gather generalist skills like writing documents, editing spreadsheets, maintaining databases, etc. Once you get your foot in the door with that, grind hard to master all the systems a company uses, and keep expanding that software portfolio. Also look at automation software like Zapier that can bridge the gap between them (make them talk to each other). Operations is a great stepping stone from support, and there will always be a need for the person keeping it all going.
