The key, he says, is to demonstrate leadership regardless of our titles in an organisation.
This is not to say that titles should be discarded, which would lead to chaos. Rather, the author suggests we assume personal responsibility by becoming the chief executive of our own roles.
"You just don't need formal authority to [lead] - only a desire to be involved and the commitment to making a positive difference," writes Sharma, who has been working with Fortune 500 companies for more than 15 years.
He believes we all have a natural power to lead, inspire and innovate, and that we can awaken our inner leader.
Readers learn about the principles and tools of leadership through the story of Blake Davis, a down-and-out bookshop salesman whose life is transformed by conversations with his unkempt mentor and four advisers with seemingly humble jobs.
Presenting the secrets of excellence in the form of a fable makes the book a lively read.
Readers are likely to remember how Davis digs out a tablet from a graveyard with "10 Human Regrets" inscribed on it - intended as a reference to mortality and a reminder of the urgent need to perform his best - or the way Anna the housekeeper, one of his advisers, passionately delineates the meaning of "Image": innovation, mastery, authenticity, guts and ethics.
The author also offers practical tools for readers to act on the philosophy of leading without a title.
These range from a section entitled "instant action step" at the end of each chapter, proffering tips such as to "record an inventory of all the areas ... where you are avoiding personal responsibility" within the next 24 hours, to words of wisdom by the protagonist's mentor and advisers, including advice from Jet the massage therapist to "get up an hour earlier every day and spend 60 minutes in self-development".
Sharma stresses the importance of practising the principles persistently on a daily basis.
"Successful people all perform the same few leadership disciplines. [Their] seemingly small, insignificant daily acts of excellence stack up over time to a best-in-class career and ... personal life."
