Success of negotiation depends on many factors, but important influence is made by energetic state of participants that is described by biorhythms. Physically weaker people are tired more quickly and they are less attentive. A person who is emotionally stronger will not be nervous so soon and will remain tactful and polite. A participant whose intellectual state is weaker will not provide good compromises.

Hence compare biorhythms and make your conclusions. Maybe you should ask your colleague to go to negotiations or maybe it would be better to postpone it when the other party is weaker?

We would like to point out that a participant whose certain state is in a low position but rising is stronger than a participant whose state is in a high position but declining.
