Just start!
No more excuses. It doesn’t have to be perfect.
The procrastination can go on no longer. There is now pain associated with further procrastination. Pain that is now outweighing the fear of launching.
The sock drawer has been sorted. The contents of the pantry and fridge checked several times. The answer is still not in there.
There is nothing to fear. There has never been anything to fear. The launch cannot fail, unless it fails to launch. So get on with it.
Just start.
