Mistakes are the usual bridge between inexperience and wisdom.

You may be right that people say: 'You know what we had Obama. He was inexperienced. The guy had great rhetoric sounded good looked good but has turned out to be an utter disaster. I want someone where I have confidence and credibility that they're up to the job and that I can trust what they tell me.'

Men know everything - all of them - all the time - no matter how stupid or inexperienced or arrogant or ignorant they are.
