I currently have thirteen mason jars in my fridge between those containing different pickled veggies, pickled hot dogs, veggie stock, and a mixed tea drink I make for myself in batches.

I've noticed I get a sense of satisfaction when I put the lid on a jar of something I just finished prepping and put it in the fridge too. In part because they just look so pretty full of different colored food in the glass, but also because they just impart a satisfying sense of 'I made a thing!' when filled that I don't get as much of from putting food in plastic containers? It's nice.
