"There are no silver bullets"

Como eu aprecio esta abordagem de Spender:

"There are no silver bullets, simple explanations, formulae, or if–then causal models, no acceptance that things are merely what they seem to be. The world, of course, is not a simple place, we have to work hard to engage it with our minds, and reduce its complexity to the point we can think logically about it and commit to action with some confidence. Actually the philosophizing is not complicated, it is an everyday practice. [Moi ici: Como não recordar o texto do Eclesiastes] Doubt is key - we must remain open to the possibility that things are not what they seem, that we have been misinformed, that things will not turn out as expected, that we have to act afresh to keep things headed in the right direction. Behind this is the recognition that the possibility of profit hinges entirely on the interplay of doubt and surprise.
...
Value, profit, and growth are the imagination’s artifacts as it engages a framed unknown; they are not the product of rational analysis. Neither are they the product of resources, designs, or logical mechanisms that transform resources into products and services.

Life (and managing) is a situation of persistent doubt and uncertainty—hence the acronym FUD (fear, uncertainty, and doubt). [Moi ici: Quantos  "funcionários" perceberão o alcance desta afirmação?] Fear may seem excessive when it comes to business affairs, but if I was wholly invested in a single enterprise I might get the jitters too. U and D are essential states of mind for any strategist with something at stake, with skin in the game."
