listen to songs
and figure out its lyrics without looking it up on the web
or keep talking english for a year

If you don't want to buy a program that will help you, then I would recommend just watching different videos online (maybe find something on youtube such as a comedian, like Dane Cook) or watching television shows. =]

Hope it helps you!
