I have experience on operating both kind of business. When I started working online, I decided to start a business of selling services like writing, SEO, digital marketing, website building, etc. I first built my portfolio on freelancer site and then linked my profile to my personal website. I was quite successful in my endeavor.
Sadly, my brick and mortar businesses were a failure. My first business was a restaurant and second business was a dairy farm. Both of these businesses collapsed due to insufficient investment, high operational cost, and mismanagement.
Do you have experience with brick and mortar business? Have you tried online business?
