Task-starting advice assumes you can name the task. Here is what to do when the mess has no boundaries, why that is a different problem for ADHD brains, and a method that does not start with “pick a corner.”
If you have ADHD, you have probably stood in a room that needs everything done to it and done nothing, because there was no single thing to point at and start.
Most advice for getting unstuck, including every task list app, assumes you can name the task. Open the document. Load the dishwasher. Reply to the email. Type it in, check it off. A messy room does not give you a task to type in.
Every surface needs something, and none of it is more urgent than the rest. “Just start somewhere” turns out to be advice for a problem you do not have.
