Being new to a profession is always a challenge. The neophyte wants to impress his superiors, but lacking experience, is left to rely upon what natural skills he possesses. And, often, will try to make up for any shortcomings in specific skills by displaying a double dose of enthusiasm and energy.
Our new president, for example, has a great many skills related to successful politicking, but none at all specifically related to the task of being president of the world's most powerful country. This is not a job that one can prepare for.
And so We the People, his new bosses, are left to observe Obama leaning heavily on his considerable political skills – and his obvious energy – in an attempt to impress.
He is trying to do so through a constant stream of new pronouncements emanating from the White House, or wherever Mr. Obama happens to be standing at the moment. On one day he wishes to put an end to nuclear weapons, on the next to reach an accommodation with the Iranians. While he’s at it, he'll be (maybe) pulling the troops out of Iraq, but redeploying them into Afghanistan and maybe even Pakistan....
