Most businesses won’t become successful for at least 10 years.
Let me explain how I define success. Success: A brand that the market recognizes, that sells a product/service that the customers sees as valuable for the price and a process that can deliver the product/service and still be profitable without the owner doing everything.
Before this stage it would be foolish to start another business venture. Because, just like it is physically impossible to be in two places at one time, it is mentally impossible to split your focus between two businesses without them both suffering at some degree.
But it is possible to keep you focus on growing one and becoming more profitable with less headaches…unless you have a cash cow that runs its self. Then I say, “duplicate!”
