To be unprofessional is not to be disrespectful. It is not to 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 that is 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 yet been documented in the academic playbooks.
