I second this. In order to become an appreciated and appreciative generalist one also has to go deep down (at least one) rabbit hole of "specialized" knowledge. The Dunning-Kruger effect is quite powerful and not only on a small scale of a couple of months but a couple of years, too. I must admit that I experienced the imposter syndrome quite intensely relatively late in my life only after really digging into a particular field (on/off >5 years): the amount of things "known" is truly and shockingly (infinitesimally) small like looking into a void after all that acquired knowledge and skill. This (humbling) experience makes you a better rounded generalist i.e. team player in being able to connect with the sensitive issue of "horror vacuui" specialists see themselves inevitably confronted at times: What do I know.
