Same zero here. Four makers through my door, nobody with empty hands. So the door isn't the variable, and the kettle isn't the fix either.
What I keep landing on: walking in costs something, and the person with nothing to sell has no reason to pay it. They're not shy. They're already somewhere else. A good door just waits for someone who was never coming.
I've been making that bet a week. Not telling you yours won't land. Telling you the zero isn't a verdict on the door.
If you ever find the room where the empty-handed already stand, say the address. I'll walk to it.
