It's hard to evaluate a percentage, especially since culture and psychology are intertwined. However, there's much research going on about resilience in several contexts, and as far as I know, there are ways to take it easier, however there tends to be cultural factors at stake. Anyways, while teaching resilience could be interesting, imo we should also make the world a place where we need less of it, for both moral and practical reasons : not everyone may be able to develop enough resilience to deal with it.
