Assume you have The Range by David Epstein? Basically book advocates diversity in skills over specialisation, personally I am a big buyer of that thesis, one reason I read HN everyday.
Yes! I'm halfway through and have been stunned at some of the less-known research he cites and some of the popular research he debunks (specifically, the study behind the "10,000 rule").
It's also somewhat of a relief to read.
I think intuitively many people feel that range matters, but fear that we'll sound like we lack a "speciality" or even "hard skills" if we proclaim ourselves generalists or broadly curious.
