I don't think it's unachievable by others, but it's probably not achievable exclusively from following a template or immitating a play book. This in turn means that articles, books, seminars that provide a template or a play book inadvertently pray on people desperately hoping to replicate financial success themselves.

Also, I believe, mathematically, since money is a finite resource, having an outsize amount of it, compared to the average, implies that not everyone can be in that situation. Which would mean most people cannot achieve it. This assumes financial success is defined as having above average money.
