I’ll go first. After your turn the water off in the shower but before you get out, use your hands to wipe off any standing water on your body. Maybe even give your legs a bit of a shake. This way, you won’t drip nearly as much when you get out, keeping the floor and your towel drier.
Also add payment reminders (for everything if you don’t autopay, but even with autopay keep the big ones in there too so you can make sure they went through).
Also add travel time blocks for appointments that are far away so you don’t accidentally overbook yourself, especially if you have to leave work for a doctor or something.
Family considering dinner vaguely “next weekend”? add a 3 day event so you remember to confirm a time with them. Everything gets a calendar event.
