How are Obama’s first 100 days as president evaluated?

Barack Obama was elected president this year, and has ruled in the U.S. for 100 days. His directing during those days has been evaluated as successful.
“The economy remains weak, of course, but he has put forward a series of initiatives to stabilize the capital and housing markets, proposed longer-term programs to create sustained growth, adjusted America's military priorities in Afghanistan and Iraq, and begun a process of reaching out to the world and changing America's image.” [i]
The reason why his directing has been evaluated as successful although the economy is still weak is because he has worked a lot to fix and stabilize it.

Many people are questioning why Obama has been so successful. The experts have made their opinion on this, and some mean it is because of “his calm leadership style, his deliberative methods and his tight teamwork.”[ii] Others are saying it is a bigger explanation to it. They are thinking it is because Obama has read the country and the political moment correctly, and that he understands that America in 2009 is a completely other place than two decades ago.
To summarize the expert’s thoughts we can say that “Barack Obama's success derives from his understanding of this shift—and his readiness to act on it.”[iii]
