I honestly don't believe he thinks he has any troubles. He absolutely dismisses all criticism. He won't even entertain the notion that people are entitled to question him. We've heard him many times - people can talk if they want, but have they done this, that, the other, have they turned down big job offers. He thinks that buys him immunity. And he obviously doesn't question himself or set himself any standards, otherwise he'd have left years ago.
He's a well practised amiable and entirely unlikable individual.
