3. Positive vibes and constructive attitude will always help
You have just had an argument and you both of you feel furious about something. This is when you should avoid trying to find a solution to any kind of problem. Compromise is impossible if either of you is not yet ready to cooperate. Let yourself some time to calm down and only then invite your partner to discuss the issue. When compromising both of the partners should be emotionally stable and ready to converse.
4. Define your own priorities
Think well before you invite your partner to start discussion. Listen to what your partner has got to say and define what things are more important than anything else. People tend to change. Start your negotiation with what can be changed in the nearest future and leave harder limits for later.
