Work hard enough to have an opinion

But how you read matters too.

You need to be critical and always thinking. You need to do the mental work required to hold an opinion.

Charlie Munger used to say something along the lines of “You’re not entitled to take a view, unless and until you can argue better against that view than the smartest guy who holds that opposite view. If you can argue better than the smartest person who holds the opposite view, that is when you are entitled to hold a certain view.”

That makes perfect sense.

While we all hold an opinion on almost everything, how many of us do the work required to have an opinion?
