From the business point of view, I would say that the reason a good web developer is a good web developer is because they specialize in web development. A designer is a good designer because they specialize in design. A database administrator is a good database administrator because they specializes in that.
A good business owner cannot micromanage. Sure at the start, you need to wear many hats, but as the business grows, you hire people (contract out, whatever) who can do what you need done. Learn what you need to - do what needs to be done, but if you have the available resources to get someone else to do it, you shouldn't feel bad about it. Your specialty is the design and manufacture.
