Focus their attention on their business product or service because they believe that’s what gives their business its value.  Cash flow is what give a business value.  And if the cash flow is self-sustaining, that is not dependent on the owner’s involvement, then the business’ value is increased even more.
Think that a business requires large investments in order to get started.  This is actually a myth!  The problem usually is that they’ve asked the wrong question.  They should be asking “how can I build this business WITHOUT an investment.”  The resulting answer and plan will help them develop the proof necessary to get funding down the road. And at the same time, gets the business started quickly instead of wasting months and even years trying to convince someone to invest in their idea.
Believe that nobody else can do what they do as like they do.  This is just not true!  Business have been growing beyond the founder or millennia.  The way it gets done is by teaching other to think and care about the delivery of your service or product in the same way that you do.  This comes from developing systems that are easily taught to others while creating accountability in a way that assures that service delivery is consistently followed.
