Also, I disagree with the whole idea of "Don't Try" in context of many pursuits. Perhaps it applies to writing as described in the article, but a lot of stuff is worth doing because it creates value for others. That value is created only if we're successful. How can one engage in such activity without having the end goal as target?

IMO the best of both worlds is to have a good life by enjoying it as parent poster said (with games, reading, sports) and when possible putting all you have into trying to achieve your goals even if the possibility of success is remote. How would the Wright brothers achieve powered flight if they didn't try. It wouldn't happen organically as a side effect of their work.
