In never eat alone, what undertaking did ferrazzi take in order to come to the realization that, "no matter what organization i represented or what professional avenue i pursued in the future, all my efforts had to be powered by a deep passion and a set of beliefs that went well beyond my own personal benefit"?

I believe the answer is: Running for New Haven City Council

He personally realized that in the council position, you would be economically more well off if you follow the will of the people who give the most findings. But he's dedicated to keep himself from the temptations and decided to work for the well being of other people.
