Being overly cautious is what you are doing wrong then. The thing is, the way we've set this RP up allows us to rationalize weird shit and sort of compartmentalize each nation so fuck-ups don't hurt other nations much. For instance, Florida being an independent nation never really complicated things for the rest of us. We only changed it because it made America difficult to grab.

The worse thing you could do is quit and ask somebody else to be Britain because that is what "pulling a Feo" is. Britain is yours now. Play with it. There isn't really a solid idea of what the anarchy and Britain has had a minimal impact on the rest of the nations, so you can do what you want so long as it makes sense. And that isn't difficult. All you need to make something work is the ability to rationalize it. 

So write for fun. Don't think fun equals doing big explosive things all the time. I've had more fun with Sahle than any of the others, and Sahle's story hasn't exactly been world changing. Play with ideas and play with the way you use words. That's how you get good at this.
