Why narrow down cognitive effort to intellectual work?
And how to accuse the ego of being in control of effort? Which seems implied by 'indulging in work'. I don't know about you, but for me it's more organic, sometimes i have inspiration, energy and a subject at hand, other times my mind can't help but idle around in habitual routines. And if i am not in control of this factor, then my development is out of control, like puberty. I try to be thankful for what little development i have and i think an attitude of being accepting of what is (thankful) promotes cognitive creativity, but i know this isn't black and white, sometimes your mind just goes calm, when you are too happy, other times the mind just goes in circles, because you are too unhappy. There may be a middle zone. Perhaps the best we can do, to foster development is to create life circumstances, that allow you to be in that neurological zone of being stimulated without being overwhelmed. And those conditions look different for everyone.
to expand on the gratefulness argument. extroverts are afraid of making mistakes, which prevents them from reflecting in introverted manner. even introverts are often bullied into measuring their introverted sentiments against extroverted standards. for me, being grateful about my development means being self accepting in the sense that i have the guts to transport my subjective sentiments to the surface of my consciousness, even to public expression, at times, but mostly just online. and this way i build up momentum and eventually i grow, even if all of my output is a bit like a badly drawn caricature of something really great. The output doesn't matter to me, my process matters more.
of course extroverts have their own ballpark of development, they are all about adaption, which is something that i have neglected fully, while optimizing my conditions for introverted development.
I agree, evolution is everything, that biology does right now, even if it's just more experiments with advancing the blood line of the trolls. There may be elves around already, but the trolls still have to evolve on their own, because they are not to become copies of elves, they are to become evolved orks. If it makes a difference is a very abstract question.
