He could have been talking about every stop of his jam-packed, eight-day, six-country overseas trip.
In London, Mr. Obama joined other world leaders in trying to tackle the spiraling global economic crisis. In , he sought help from NATO allies in dealing with the deteriorating war in . In the , Mr. Obama pledged to end the threat of nuclear weapons. In , he sought to start in the Muslim world. And in , he pushed for Iraqis to "take responsibility for their own country."
The pile of problems on Mr. Obama's desk was high before he left, and remains so now that he is back.
The president returned to Washington in the early hours of Wednesday morning, bringing his lengthy debut on the world stage - including his first stop in a war zone as commander in chief - to a close.
Aides said he brought home achievements both large and small, evidence, they said, of the benefits of the extended travel that turned attention away from all the pressing matters at home for the first time in his less-than-three-month-old presidency.
"It's tangible and intangible," White House chief of staff Rahm Emanuel said of the trip's value.
For a nation gripped with worry about its economic future, among the concrete things Mr. Obama achieved was an agreement out of the in London. The wealthy and developing nations promised to get a handle on risky financial transactions, to act to further stimulate their economies if growth doesn't improve, and to help poorer nations feeling more effects from the global financial meltdown than they can mitigate on their own.
Mr. Obama didn't get European nations to step up with the kind of immediate stimulus spending that might quickly jump-start their economies and in turn boost America's, but he billed the meetings as a success nonetheless.
Emanuel also cited the allies "to do their part" in Afghanistan, even though nations agreed only to make modest new contributions to short-term security and training efforts, and not to join the heavy fighting in the volatile south and east of the country. Mr. Obama also made some strides toward addressing the international nuclear threat by with toward a new arms-control pact.
There was a less quantifiable side of the ledger, as well.
Between Mr. Obama's outreach to local students at town halls in France and Turkey, as well as speeches and well over a dozen private meetings with individual foreign leaders, aides felt the president established a new-sheriff-in-town vibe.
"Yesterday during a town hall meeting with Turkish students, the president kind of made fun of the American media," noted CBS News White House correspondent Chip Reid. "He said, 'Some of my reporter friends from the States were asking, How come you didn't solve everything on this trip?'"
"Well, you know, it's only been a week!" Mr. Obama said. "These things take time and the idea is that you lay the groundwork and slowly, over time, if you make small efforts, they can add up into big efforts. And that's, I think, the approach that we want to take in promoting more peace and prosperity around the world."
A day-by-day guide to one of the most closely watched presidential trips in recent memory.
Mr. Obama said over and over that he was in Europe to listen, not dictate. The subtext was that his leadership would be a sharp U-turn from that of President George W. Bush, and that he hoped putting a new stamp on U.S. foreign policy would pay dividends from more cooperative allies.
The two-day stay in Turkey, a Muslim-majority nation that straddles Europe and Asia, was a key part of that strategy. Mr. Obama hoped to refresh relations with a Muslim-world partner with whom relations became strained over the Iraq war.
"America is back," was how Emanuel put it.
There's no doubting that Mr. Obama was well-received.
The question is whether the world's problems will get any better as a result, and the answer won't be known for a while. Diplomacy is a slow process and so is changing the policy of any one nation, much less several - "moving the ship of state," as Mr. Obama likes to put it.
Also unclear: where the line will fall with the fickle American public, between excitement at having a leader who makes a big splash overseas and annoyance that that same leader is lavishing attention on the pet priorities of other parts of the world.
The previously was confined to the main U.S. military base there, Camp Victory. Attention from the new commander in chief proved a huge morale booster, judging from the wildly cheering audience that greeted the president at a former palace of the late Iraqi leader Saddam Hussein.
The president's official schedule had said he would be flying directly to Washington D.C. from Istanbul on Tuesday and made no mention of an Iraq visit. Reporters did sense that an unannounced trip was a strong possibility, however, as CBS News Producer Robert Hendin points out in a behind-the-scenes dispatch.
Although violence is down overall in Iraq from its peak, it has surged lately with a string of deadly bombings, including one in Baghdad just hours before Mr. Obama's arrival. The White House scrapped plans for the president to helicopter into Baghdad's heavily fortified Green Zone to see Iraqi Prime Minister Nouri al-Maliki and other leaders, citing not security fears but a sand and dust storm that reduced visibility. Instead, the leaders traveled to see him at Camp Victory.
"They were all but crawling all over each other afterwards to touch him, to shake his hand, to get a picture, to get an autograph. It was an amazing reception," Reid said.
Mr. Obama met with Gen. Ray Odierno, who briefed him on the recent violence and security challenges in Iraq. Reid reports that the president was told, despite a recent rash of bombings, security incidents are now at their lowest level since the war began.
"They still believe they have a handle on things," Reid said, "although certainly it is something that they're concerned about. They hope that this is just a one-time thing, not an indication of a steady up-tick to come. General Odierno seemed to be positive that they're on track to get the troops out on the timetable the president has laid out."
Mr. Obama had a message for Americans, too. With over 4,260 lives lost and $600 billion spent, he paid heartfelt tribute to the "enormous sacrifice" made by the U.S. in Iraq.
"It is time for us to transition to the Iraqis," he said, earning the loudest applause line of his five-minute address to troops. "They need to take responsibility for their country."
"We assured the president that all the progress that was made in the security area will continue," al-Maliki said at Mr. Obama's side.
The president projected confidence in that. "We should not get distracted" by the violence, he said, arguing that "our shared commitment is greater than the obstacles."
Such an optimistic note could have come at any other point in his travels.
