WILL-THE-LION'S PROFILE

So guys I have a question for you all. I'm having trouble progressing in the development of my rpg game because I seem to lack the idea of where to work. I try to work on battles/monsters, but without dungeons to put them in. I don't have any dungeons because I want them to match the areas around them which aren't done yet. But it's hard to design areas that seem useful without a story that's more fleshed out. But at the same time it's hard to flesh out a story without a setting for it to take place in. So I've been working kinda all over the place.

One day some maps.
Another day some monsters.
And say another I'll do some story writing.
But it seems really DISORGANIZED. Any ideas on how to work more effectively?NO
