The article mentioned how, just after he was awarded the Nobel Prize, he went into a meeting with advisors. They knew not to congratulate him on the award because, they said, unlike other presidents, he mistrusts being flattered. He just wanted to get down to business.
It's often said he's cocky, and perhaps he is. But the cockiness is simply confidence and shouldn't be confused with having a huge ego. In fact a huge ego is usually a sign of the opposite.
So I generally agree with what you're saying.
ON EDIT: The story was from a Joe Klein article in Time. Snippets:
....On the morning he won the Nobel Peace Prize, Obama met with a nervous group of aides. The award might be a political problem, they said. It might be ridiculed. He hadn't achieved any of his foreign policy goals yet. "It is kind of crazy," Obama acknowledged with a laugh, "but that's not the real problem we're facing here. How do you accept the Nobel Peace Prize when you're the Commander in Chief of a military that is fighting two wars?"
The President's next meeting was about one of those wars — the one in Afghanistan — with his National Security Council in the Situation Room. Everyone stood as the President entered. "I was waiting for people to start applauding or someone to say, 'Congratulations, Mr. President,' or something like that," an aide recalls. "But no one said anything, and the President didn't say anything about the prize either. He just started in on the agenda...
...Unlike most politicians, Obama doesn't thrive on sycophancy; he mistrusts it. That's why no one in the Situation Room congratulated him on the prize. And he's not very good at faking the hail-fellow camaraderie that is part of American public life, either. He doesn't seem to enjoy the game of politics all that much. In his memoir of the 2008 presidential race, Obama campaign manager David Plouffe says his candidate grew "increasingly sullen" on the road during the early months of the campaign. Communications director Robert Gibbs asked Obama if he was having any fun at all. No, Obama replied. Was there anything that could be done to make it more fun? Again, the answer was no. "He found most coverage of the race banal," Plouffe writes. "And there wasn't nearly enough time for his favorite part of the campaign — noodling over policy, or, as he called it, think time."
...
In such an atmosphere, the President has to convey a little heat too. He has to be as concerned with stagecraft, political appearances, feel-your-pain empathy as he is with substance. That seems like an effort for Obama. In his first meeting with aides on his Nobel morning, he skipped past the political question — How could they react to the perception that the prize was premature? — to the heart of the matter: What was the rationale for a war President to receive a peace prize?...http://www.time.com/time/politics/article/0,8599,1955401-2,00.html#ixzz0dHWTUN3B
