Do You Ever Go Back to Read Freakonomics or Super Freak?

Freakonomics Radio host says he's never really gone back to read more than like a paragraph or two of any book he'd written. "When I think about our books I imagine them to be my academic papers stapled together slightly improved and so when I actually go and look at our books every time  I am stunned at how good they are" 'You have to really like maple syrup to do all the work' is his advice for people who want to start their own business.
