I have a bit of trouble with the use of "Average Person," personally. I know a lot of Average people that are business owners, and Successful and Proud.  There are two perspectives I see: The average or typical person that decides to start a business (and perhaps doesn't shift gears in response); and, the average or typical worker that is the Incredible resource to the business owner.

I would examine this as, "What mindset does the business owner Need?"

Because, not everyone needs to learn everything or excel at it.

A successful Business Owner needs to be able to stand back when they are In the Way, step Forward when it is their time to Lead, and know that difference. Sometimes that means, get out of your own way.
