The most important condition for finding a solution is a sincere willingness to give up your own solution and look for a new joint one, which will not be optimal for you and probably will not be optimal for the other, but will be acceptable enough for both of you. Because if “coming to an agreement” really means deep down for us “convincing the other of my decision, selling him, figuratively speaking, my decision,” then we really won’t get very far. Step 1: Willingness to Compromise This is when it is neither me nor you, but somewhere in between. If you understand that you no longer want to seek a compromise, that you have so many different feelings - injustice, resentment, anger, that you want to be heard in yours and achieve yours, then there is another way. Then you first need to get out of this level of complex feelings. When there are so many of them, it is impossible to agree on anything normally.
