Creating a sustainable mindset
I like that phrase, and I think it makes a great slogan. Sometime a slogan can go a long long way, and getting a group, however big or small to think of sustainability is not an easy thing to do.
No community can really stand alone on its own. They are always going to need the support of other communities, but when people hear the term sustainability, all they can really think of is what they are going to have to give up. They think it means sacrifice, not sacred life. Sustainability does not mean doing with out, but you will have a hard time convincing people of that.
It's interesting how this term it often seen as having to give something up as you say, but that's perhaps a reflection of how we live in the modern age. If you look at indigenous cultures from around they world they seem to have a much more harmonious relationship with their environment. Not sure what we have to do as a society to get back to that way of living...
