The rulebook for starting and growing a business has changed

To be unprofessional is not to be disrespectful. It is not be reckless or lazy. It is not to be unpunctual, badly presented or poorly spoken.

To be unprofessional is to be real. It is to create a vision unborrowed from the past. It is to develop products that genuinely wow your audience. It is to think of marketing strategies that the management consultants don’t have diagrams or buzz words for yet. It is to think original thoughts and speak of proactive ideas that haven’t been documented in the academic playbooks.

While the professionals are trying to outspend each other with oversized advertising budgets, unprofessionals prefer to have the media build their brand for them in a way that cuts through the advertising clutter. While the professionals are competing, unprofessionals are forming partnerships that see their brand travel further.

This book is your permission slip to throw out the rulebook; forget the old paradigms; and build your business to a position of market leadership using strategies that still haven’t found their way onto the notepads of the management consultants.
