Andy Cevallos: I see this problem with entrepreneurs a lot. They start out and they want to, they don't start, they want to accumulate all the knowledge of everything. So it's not knowledge is power. It's the execution ofknowledge is power. He says people who have PhD in entrepreneurship but never run a business would rather be an entrepreneur than someone who doesn't know what he or she is doing. "I'm going to tell you right now. You always wouldn't be the guy who says, I don't know what the fuck I'm doing"
