anecdotes are not data. you have no idea of the correlation between your upbringing and your creativity and independence. twin studies disagree with you.
An anecdote about one's own life is not just an anecdote...it's personal experience. And personal experience offers a perspective that no amount of data can. We are discussing how to nurture creativity and productive skills, after all, and inherent in that goal there is a severe measurement problem that severely limits any data-driven approach.
The twin studies I'm aware of basically say that you can expose twins to identical circumstances and they will still turn out different. I'm not sure how that contradicts his main point though.
I assumed he meant that two twins growing up under completely different circumstances will still turn out to be the same. Which then implies to me that success is already determined before birth. If true, working our young people hard or not working them won't have any profound affect on their lives.
Incidentally, my upbringing sounds a lot like kstenerud's. My brother and myself sound much like he and his siblings. Another anecdote, sure, but still an intriguing point of view.
the problem isn't the conclusion he drew, it's that he made a causal link (at least he used causal language, "as a result we grew up X") instead of drawing a correlation. This would be wrong regardless of whether the conclusion was actually correct because no matter the conclusion, his experience is insufficient to make that causal link with high confidence.
