I have four pets so have a chart on the kitchen wall when they need their flea and worming treatments then a reminder in my phone for so many days before the next treatment to order the meds.
Alarm in phone to order meds, send birthday cards, msg a friend on a sad anniversary.
List in phone what I buy for birthdays and Christmas so don't duplicate. Note if a gift was a fail.
I make all my own cards then personalise them at the time. I have a cardboard perpetual calendar and write months worths of cards at a time. I bulk buy stamps on line, especially if I hear they are about to go up in price again.
All bins have spare rolls of liners underneath. Kitchen roll in kitchen bin with bicarbonate to soak up leaks and smells.
I empty the dishwasher while the dog is doing her last night/ first morning wee.
Set days for certain laundry.
I labelled my quilt and cover but it got washed off so I fight each week until I work out the right way again.
Never go up or down stairs without taking whatever is waiting.
Take post at first walk with dog as the post box is emptied at a different time each day.
If I notice I'm low on petrol I put my note with PETROL written on it on the dashboard or my seat ready for when I next go out to remind me to fill up.
