Writers Block

Ugh for some reason I can't seem to think of any thing good to write about...or just writing in general...I would like to write more fiction stuff but I'm not sure were to start. Its hard creating interesting, likable and deep, complex characters when you have as little experience as me. I know i shouldn't shoot for the moon when I'm starting out but i can't help it at times. It sad cause when i was younger i could write more freely, but with less structure and now all i think about it the structure and trying to make the story work in it...maybe i should be trying for the other way around...?
