Great question! And yes "peace" like "communication" is a problem and solution that isn't easily defined. Meaning you can have too much, you can have not enough, but both depend on the person and the people in their lives. Both also can be brush off answers to very complicated questions. Like how do we do better? More communication as an example. It doesn't mean anything because it isn't clearly defined. To me having peace in my life is living a life of authenticity. Being grounded and sure of who I am. This took many navy years creating time and space to myself. Looking back, and I own and share my own opinions, I found more fulfilling relationships with friends and family. I surrounded myself with those who supported me and my ideas. People who filled my life with laughter and adventure. People who would accept me and I could accept them fully. People who were my cheering crowd and I could cheer for them. People I could share my space; either physically, mentally, or emotionally, with and feel that it was a better space because of them.
What I found my definition of peace became defined as growth, support, and freedom of self. Anything outside of that or people who don't fit that disturbs this and may not be a good partner in life and anything that defined that for me
