This is very nice. When you say "When someone works on multiple projects at once, this means that he is not a good businessman. You can be a digital currency broker, but you can not be a good blogger at 5 sites at the same time. " It seems that micro-managing multiple projects means you can't stay focused on one thing and if you focus on one thing, you can focus and do quality work on one thing instead of sub-par work on multiple projects.
