The Finnish rule "Live and let others live" http://finnishskills.blogspot.fi/2012/10/live-and-let-others-live.html creates a well working social life and well working international relationships. It is a good formulation of a very basic observation like "I live and they live in their own ways too". It kind of sets guidelines and borders straight and tell what to defend and what not to bother about. It is amazingly effective. It presupposes a some kind of moral which agrees with thinking with a picture of the whole. Please get to know it, pick a better saying for it and try it out somewhere from where you can learn it if it works out well.
There is also another piece of Finnish wisdom that works well with this perspectiva and solves tangles and makes life better: http://finnishskills.blogspot.fi/2012/10/social-skills.html
