For famous venture capitalist Marc Andreessen, staying open-minded is so important that he's willing to endure some funny looks from other people.
In a talk with students at Stanford Graduate School of Business, Andreessen reportedly said he has a unique trick to keep himself objective and consider other points of view: Imagining famous tech figures on his shoulders like the apparitions of devils and angels that appear in movies.
"I have a little simulation of Peter Thiel," Andreessen joked to Stanford students, referring to the PayPal co-founder and technology investor. "He lives on my shoulder right here. I argue with him all day long."
