What are various European countries motto?
France: "Liberty, Equality, Fraternity"
Germany: "Unity and Justice and Freedom"
Italy: "Italy is a democratic republic, founded on labor"
Spain: "Further Beyond"
I can talk at least for France, but this motto is not top of mind for most people. It doesn't necessarily reflect who and what we are as a country, but merely some values we raised as a flag centuries ago (not to say they are necessarily bad values though).
So, it could be a great idea to refactor our motto into a set of values & behaviours that resonate with both the people today and how the world evolved. And then ensuring these values are part of our everyday lives.
It would be a great way to let foreigners identify France as a country to live in that would be a good fit for them. For instance, US and Canada sound like great coutries for hard workers and people with an entrepreneur mindset!
=> [[How we see other countries]] : It's far easier to apprehend a country if their values are crystal clear to the foreign eye.
=> [[Freedom is not the golden standard]] : An interesting take on a keyword from the French motto.
