First There Was UnMarketing Now There Is UnSelling - this post of "Six Pixels of Separation" pointed me to this book about everything but to sell.
UnSelling is about the bigger picture of sales.
Analogical, UnRisk is about the bigger picture of risk.
In both cases you need a lot of experience and in depth knowledge to get the bigger picture.
But yes, it is sometimes indispensable to unlearn. The rules of selling - as well as the rules of risk management - have fundamentally changed.
The programmability of sales by understanding value, access and education and the programmability of risk by understanding money, duality, boundaries and optimization…come to my mind.
