I find these types of articles/blogs to be relatively pointless because the market/economy/country/etc has room for a select few successes. Imagine if Obama wrote "How to Be a Successful Presidential Candidate" and every 2016 candidate read it and adopted it to a tee. We'd still have dozens of failures and only 1 success. If success were really a formula, then we'd all be successful. We can't all get into harvard, we…
I disagree on both counts. To use an overly relevant analogy, the market is not so efficient that successful startups cannot be built (and planned in advance of becoming successful), and it is possible for everyone in the world to become more competent and skilled and for this to just make everything better (e.g. better products for everyone).
You can have new insights that are generally true, and everything isn't zero sum.
