Sticky notes
This one is easy as it gets. You’d probably have seen it thousands of times in the movies, where someone leaves a little note on the fridge with ”Don’t forget to take the trash outside” or “Don’t forget to smile today”.
Apart from being a well-known but ancient method of remembering daily tasks, we believe it’s highly underrated. I mean, all you have to do is to leave a note whenever you need to remember something. It can be a reminder to pick up the kids from piano class or to go to dinner with an old friend you encountered the other day. Whatever it might be, leaving around the house a sticky note can be a real lifesaver for your memory.
