Agree, specially because everyone has above average IQ. That being said this conversation always feels to me like "are soldiers afraid before a battle" type discussion. Either they are or they aren't has no bearing on what they do. They have to be brave and get out there. Same here, just realise everyone has doubts, and instead of spending time making a big thing of it and "dealing with it", just put your head down and work hard. Everyone has doubts, focusing on them is pointless.
