Barack Obama has given his first big speech since winning the American presidential election.
Obama doesn't become the president until 20 January 2009, so until then is working out what he wants to do.
He said one of the first things he will do will be to try to sort out the cash crisis that is affecting the world.
He added that he wanted to create jobs and help families, but admitted solving the problems was "not going to be quick and it's not going to be easy".
Obama, who is now called the President-elect, was speaking in his home city of Chicago.
His family will be leaving Chicago for Washington when he becomes president, and the whole family will live in the White House.
That means new schools for Obama's daughters Malia and Sasha, and his wife Michelle has started to look for them.
Obama also spoke about the puppy he has promised to buy his daughters, saying: "Malia is allergic, so it has to be hypoallergenic.
"On the other hand, our preference would be to get a shelter dog, but a lot of shelter dogs are mutts like me," he added.
