Tomorrow's first task can begin tonight with a small act of preparation. Choose the work, locate its inputs and remove one obstacle that would otherwise delay beginning.
Keep the preparation proportionate. A fictional writer might leave the next section heading, three source notes and an unanswered question at the top of the document. They do not need to reorganise every folder before writing another paragraph.
Confirm the prerequisite
Ask whether the next task depends on a reply, an available tool or someone else's permission. Request that input while there is still time. If it will remain unavailable, identify a genuinely ready alternative rather than writing a plan that depends on hope.
Leave a visible starting instruction: compare these two figures, draft this example or call this person about this specific question. The instruction should be clear enough to follow without reopening the entire planning conversation.
Leave room for reality
Preparation gives the next day a starting point, but new responsibilities may change priority. Reassess honestly when that happens. The prepared task remains easier to resume later.
End the preparation after it has made the start easier. An evening spent endlessly arranging tomorrow can consume the rest the next day needs. A modest ready state is enough: the materials are available, the action is understood and the important dependency has been checked.
