‘Organise my files’ can feel like a large job. ‘Open the folder and look at what's there’ is a much smaller starting point.
Choose a task you've been postponing. Write down the first action you could take without needing to solve everything else. Make it specific: open a document, find one email, or choose five photographs.
Try that action. When you're done, decide whether to continue or leave yourself a clear next step. A small start still counts.
