I used to be hyperfocused on perfectly controlling each meal, then I realized I could balance the whole day. Eventually, I was thinking in terms of the week. Now, I see the whole year. Years, even! I tend to celebrate more and eat more over the holidays and on vacations. Typical weeks with nothing special going on seem to even that out effortlessly. I tend to be more active, spend more time outside, and eat more plants in the summer. I tend toward warm comfort foods and extra sleep in the dead of winter. None of that is wrong. None of it requires corrective action or special diet strategies. It's just how life is.
Compare that to trying to eat a set number of calories or specific macros every day, regardless of circumstances, or only being able to eat special foods at certain times. Diets always seem to be at odds with real life. If you want to go to a restaurant with friends, enjoy a spontaneous celebration, or eat food prepared by others, forget it. The emphasis on rule-following and getting each day and meal "right" causes so much unnecessary stress. Instead, think in terms of your own values, eating to feel your best, and the big picture of your choices over time.
