How do you do schedules? - Lemmy.world

I have struggled with this forever. I have gotten OK with lists of things I need to do and organizing those in a few different places I actually will look at, but what do I do about scheduling/calendars? I can do what my work calendar says but anytime I make my own schedule, it becomes invisible to me and I don’t even consider it very quickly. Anyone have any tips for scheduling tasks and actually following through with it?
