This has crept up on me as I get older. I worked in fast food a lot when I was younger and would just cobble something “healthy” together on breaks. For awhile I drank Huel all the time because I got burned out on food.
After going vegan I discovered a whole new world of flavor, and a bit before that realized I’m obsessed with spicy food (I grew up in the Midwest with very low exposure to spicy food). Now that I have basically all the material things I want, I really value having an incredible meal more. Unfortunately that’s resulted in poor choices and I’m getting fat.
Maybe not a direct answer to your question but I’d try to keep it the lowest number of subjects at any given time with deeper learning in them.
In school I was genuinely interested in learning, but every instructor seemed to hand you a mountain of homework each day and acted like their subject was the most important. I spent most my time scrambling to get it all done and in the end only learned what little I could to simply pass.
I remember this especially with math, I loved math but if I took the time to study better and actually learn the concepts, I wouldn’t have had the time to finish my other homework.
