Self-awareness

In an interview with Yahoo! and Politico, George Bushleague said of his legacy:

"I think history, when they look back, will say this is a fellow who knew how to make decisions, and made some tough ones, stood by them, wasn't driven by the latest opinion poll, but was driven by some core principles from which he would not deviate."

In other words, a stubborn, narrow-minded, egomaniacal dolt incapable of incorporating new information into his worldview - who was for some unfathomable but unquestionably false reason quite pleased with himself.
