I may be insecure, but I’m not “having been President of the United States alone is not impressive enough I need to be able to show people I had access to the nation’s most secret information even though they probably could have already figured that out because I was President of the United States” insecure.
Few of us are. That's because we may all be insecure, but we are not, "I have counterfeit Time magazine covers with my picture on them on the walls of my country club" insecure.
