Wow, since when "leading" isn't the most difficult/well-paid job in our society?
Overall, I think the author is mixing up apples with oranges and that's why this article sounds so weird. It's a very contradicting piece right here.
I wasn't attempting to dismiss leadership in any way, shape, or form. Merely calling out the difference between personally "doing" (in the sense of small business) versus the "orchestrating" that is more typical in a larger company.
I've worked in both and have seen how people that spent their career in a large company may struggle in a small business setting. No shame. Just a (often overlooked) distinction.
