"The easiest job you'll ever get is to try to make your first film . . . After you've done that feature, then you have a heck of a difficult time getting your second film off the ground. They look at your first film and they say, 'Oh well, we don't want you anymore.'"
True. Look at how many directors there are who've never made a second film. Lucas said the above after his first feature length film, THX 1138, was released and while he was having a hard time getting the studios interested in funding his second, American Graffiti. Interesting problem, since THX 1138 is still my favourite Lucas-directed flick. (No, it's not Star Wars: Episode II - Attack of the Clones. That's the worst Lucas film.)
