Moving forward does not always require agreement or even consensus. Sometimes acceptance is enough to get over a roadblock and move on, thus becoming unemotional enough to think at a practical, subjective level necessary to resolve whatever it is (or at least get clear about the options). In most cases, accepting what’s there allows one to focus on third-ways, work-arounds, or other ways to deal with brick walls.
A while back I adopted a new mantra: “It is what it is.” This flip, near-palindromic saying has helped me enormously whenever I found myself getting emotionally tangled in an issue. Those five words are my trigger-phrase to remind me my usual logical thinking failed to show and thus alerts me to first accept the situation as-is, then figure out how to deal with it.
It works for me, although YMMV.
