I dont remember exactly the title but it was an 8 to 10 page article that went into detail comparing high IQ people to average or low IQ people and why people with lower average IQ did better in business. The article was filled with graphs and case studies and was very interesting.
But the last paragraph really summarized it best, "Smart people consistently over analyzed risk and talked themselves out of taking risks while someone with a lower IQ didnt even think about the risk and jumped in with both feet and took chances."
It gets back to the saying "No risk / No reward".
I remember that article to this day and always do a gut check when it comes to evaluating new risks. Sometimes I second voice my old European grandfather who was all about hard work in a different industry but his life lessons hold true.
Turning off the brain chatter and clearly evaluating a situation is critical but it s very hard because intelligent people, and humans in general, like to avoid risk and the temporary unpleasant pain that accompanies it.
