Awakening the Entrepreneur Within: How Ordinary People Can Create Extraordinary Companies by Michael E. Gerber is a product of love. It is my gift to you, worthy reader, if you wish to know the truth about starting your own business. That you are doing it for the right reason does not have to be true. (It rarely is true!) Your desire is enough.
The reporting in The Power of Habit: Why We Do What We Do in Life and Business by Charles Duhigg is based on hundreds of interviews, and thousands more papers and studies. Many of those sources are detailed in the text itself or the notes, along with guides to additional resources for interested readers.
