 For this you try to reduce your insecurity in order to make the best possible decision/the best decision.
 Reaching agreement requires the same from the other party./ When reaching agreement it is the same situation for the other party.
 So if you would like to have a positive/favourable decision for yourself, reduce your partner’s insecurity about the decision.
