Lower the bar until it's embarrassing, then go lower
Take the thing you're avoiding and shrink it until you'd feel slightly stupid saying it out loud. Wash one fork. Open the document. Put one sock in the basket.
That embarrassment is the signal you've got it right. Your brain prices a job before it lets you start — "clean the kitchen" comes back expensive and the block fires. "Wash one fork" comes back as nothing, so the block never gets a chance.
Washed one fork and stopped? Genuinely done — nothing more is owed. That's the tip working, not the tip half-working.
