“Negative emotions like fear and sadness can lead to brain activity and thought patterns that are detrimental to creative, productive work: (a) avoidance of risk; (b) difficulty remembering and planning; and (c) rational decision-making.”
'a' and 'b' I'll grant, but rational decision-making is detrimental to productivity and creativity? Fear incites rationality? This seems out of place to me.
In the article about Steve Jobs at Corning re: Gorilla Glass:
> This turned Jobs around, and he said he wanted as much gorilla glass as Corning could make within six months. “We don’t have the capacity,” Weeks replied. “None of our plants make the glass now.”
> “Don’t be afraid,” Jobs replied. This stunned Weeks, who was good-humored and confident but not used to Jobs’s reality distortion field. He tried to explain that a false sense of confidence would not overcome engineering challenges, but that was a premise that Jobs had repeatedly shown he didn’t accept. He stared at Weeks unblinking. “Yes, you can do it,” he said. “Get your mind around it. You can do it.”
There's a book i've been enjoying [Thinking Fast and Slow](http://www.amazon.com/Thinking-Fast-Slow-Daniel-Kahneman/dp/...) that addresses this in great detail.
