Most notes start with what caught your attention. Try starting with the weather instead: “Dry, bright, light wind.” It takes five seconds and it answers the question you will ask first when you read the note again.
For outdoor work the weather line explains more than any picture. Dry grass means tools can be laid straight on the ground; a wet morning means they go on a board or a sack, and get dried before they are put away.
Keep it to three words when you are in a hurry. Three words are still more than most notes have.
