The reason I call this "blogging success" is that many online (and offline) entrepreneurs use blogs as a form of marketing and socialization.
They may not blog as a business, but they blog for their business. And others blog solely as their business. You can just insert your own favorite words while reading if you prefer. ;)
This exercise can work no matter what type of business you are in, or what kind of work you do for yourself. It doesn't matter if you work for yourself full-time, part-time or as a hustle.
It doesn't matter if you work online, out of a studio, or in your own store where you churn out incredible cupcakes.
