1. When I have a disagreement with my GF is to validate and not raise my voice. I can�t help it I am Italian. Lol Seriously though, try to stay calm even when the other person is yelling at me. 2. I have learned from here that a person�s feelings is their feelings and I don�t have right to tell them what they are feeling is wrong, ridiculous, makes no sense. That is how they feel in that moment and it is my job to understand and validate those feelings. Not easy for me but I am working on it. 3. Do I want to be right or happy? Instead of always trying to prove my point, just let it go and put my pride to the side and be happy. 4. Really try to express how I feel and how something is making me feel instead of just bottling it up or expect the other person to just know how I feel. 5. Most important, just learn to be happy no matter what life throws at you. These last 2 years have been the hardest years of my life, literally. I am always trying to find little bits of positive and happiness. It�s not easy, it takes work but it�s worth it.
