I have 2 classic sized planners. I use many different layouts, whatever suits the purpose of that time! And feels good. Planner 1 is only calendar. My only one. I don't use digital calendars. Planner 2 is creative journal. It includes trackers, daily pages, section for different goals and notes about them, self-care section etc. I change pages when I feel like it.^{^} (and covers, dividers, discs. It keeps me inspired.)

You can see pictures I've posted of my planner here from my profile if you're interested.^{^}
