I think you are doing really fine as I also have this two habit you listed here, except the last one. Mindful spending is what I learned from my oldies, though we also gave in to our wants sometimes but still with limits. With mindful spending, I can save more, aside from that I can use my money into more meaning things. Same with reducing Food Waste. We always prepared foods for what our belly can take. My oldies hate wasting food, that's also that one thing they taught me. It should be jusy enough, nothing will be wasted and everyone's will be happy ✨.
