Until Over and Done With
Some threads truly have no end. You just keep pulling and pulling and pulling to no avail. Those are threads you shouldn’t be too worried about. Those threads take care of themselves.
Then you have threads that last for a long time but do have an end. Threads that get shorter and shorter until eventually, you reach the knot at the end.
Keep that knot in mind when pulling. Be mindful of its existence. Know that, near or far, you will eventually reach that knot. And then, it will be over and done with.
