I have a magic marker in the kitchen, which I use to write the use by or best before dates on jars and packages
I use clear containers and jars so I can see what's in them and what state they're in
I don't have one cupboard for all the cleaning gear. I keep things I use to clean, close to where I use them - bathroom and toilet cleaners in the bathroom, laundry detergents close to the washing machine and shoe care stuff close to my shoes.
I have magnetic boards, lots of magnets and clips and even have magnetic sheets which I can cut and stick to items so that they can go on the boards - phone, frequently used screwdrivers and pen pots are all stuck up on IKEA metal boards
I keep a letter opener handy so that when mail come in, it's opened straight away. I decide whether it needs to be filed or whether something needs to be done and clip it up, ready to be dealt with.
I have lots of mirrors and dry wipe pens - If I need to remember something, I write it on one or more mirrors, so that when I look in the mirror, I'll see the note.
If I need to remember to post a letter or bring something out with me, I place it on the floor, in front of a door I have to pass through to leave the house.
I have magnetic note pads stuck about the place, so that I can write notes to myself wherever I am.
II have a whiteboard in my bedroom - the first and last thing I see when I wake up is what I've written on the board.
New job uses Microsoft Teams - I have my shifts to hand whenever I open the app.
Anyone got anything else?
Apps? Practices?
