When you’re boating there are certain things you are required to have on board. The length of the boat and the number of passengers determines what you’re required to carry on board. One term used to identify these things is “mandatory carriage.”
As an ADHDer there are some things I absolutely need to have on my person or within easy reach. I call this “Kelly’s ADHD mandatory carriage.”
Some of the things I never use, they’re more for peace of mind, but that’s a cheap price to pay. The peace is sometimes illusory, not needing to worry about one thing doesn’t mean I won’t worry about others.
