Advice on reducing food waste

I grew up in a house that constantly wastes food, particularly produce because it goes bad so fast. I recently realized this pattern absolutely carried over into my own kitchen and I hate it. What methods do you use to reduce or eliminate food waste? I’ve tried writing down what I have, re-organizing the fridge, etcetera, but not a lot of luck. I care deeply about this but for some reason can’t seem to improve.

(Also, if you have any adhd-specific tips, those are very appreciated.)
