(General Session End Point)
The general PaulsRobot session end point
EITHER you are getting no more change out of the topic you have been addressing per the instructions, which includes no more yawns. And you should also feel good, such as expansive, calm, peaceful, refreshed.
OR it is fine to end the session if the topic isn't complete but you seem done for now, such as you had a good win and don't feel like more of this right now.
Don't try to do too much in one session
You may also address more than one topic in the session if you wish, but if you had some good energy exchange going on it is usually best to wait till a later session to address another topic.
