I may have accidentally implied the semi-retirement angle more strongly than my point regarding tending to the first business as if a garden instead of trying to scale it, which was more what I wanted to focus on. Apologies if that wasn't as clear as it could be.

Perhaps I should also have mentioned that he is diversifying, where diversifying is certainly distinct from scaling the first business up.

As far as his first business goes, I still think it is worthwhile questioning the common automatic assumption that the next goal should be to scale it.
