I used to make a new weekly spread every Monday morning and it took forever

Oh man, Mondays are brutal enough without adding an arts and crafts project to the mix. Look, I get the appeal of a fresh spread every week, it feels good and all. But here's the thing nobody said yet, you're basically making a new system every seven days and that defeats the purpose. You want the spread to be the tool, not the task. Maybe try a monthly overview with some blank space for notes instead of a weekly reset. That way you only design the layout once and spend the rest of your time actually using it.
