Ugh, the same old banal premise that the individual can accomplish anything if only they try hard enough/believe hard enough. I fully realize the futility of pointing this out to this camp, but the reasons that the majority of people end up stuck in mediocrity are primarily external, not internal (little things like systemic oppression, constitutive disadvantage, etc.) Your magic road that “leads to an incredibly exciting, fulfilling life” is, in fact, far from free and open.
The style of shallow writing/‘thinking’ that typifies sites like this are why the self-help movement is looked askance at by scholars, mental health professionals, etc. And it’s a shame that it’s not a more credible genre, given the potential to help a broad populace who can’t afford to, or prefer not to, access professionals.
