I like the article and where it is going, though I think the specific recommendations they make only scratches the surface. There are much better techniques that can be learned from some traditional wisdom lineages, shamanic initiations, and esoteric martial art lineages.
From my own experiences with Vipassana and other practices, it isn't enough to turn something negative into a positive. If you are not careful, that turns into clinging (wishful thinking). Rather, we're talking about being able to look at everything with clarity, with neither aversion or clinging. To be in equanimity with existential anguish.
This is something I am deeply interested in. Resiliency, drawing from all the different traditions and disciplines I had picked up, is something I want to instill in my step-daughter, and any other children I might raise. None of the things we know as "formulas of success" will apply by the time my kid(s) or your's reach adulthood. Our tech is moving too fast for that.
I want my step-daughter to learn how to Choose in face of uncertainty; to act with impeccable intent; to see the world with clarity. To be equally at home lost in the woods as in the middle of the urban jungle; to speak and communicate well with people of high status and the humblest of the homeless, both intimate friends and strangers from exotic culture. Resiliency is the basis to thrive.
