I'd agree that most of the rules are common sense sort of things, there are a dozen or so rules that if you break it means an admin sep, and lesser offenses that potential could be an admin sep, but more likely are a warning. The cardinal rules not to break were stuff like being out of site without permission, traveling unsafely (i.e. after dark, on a motorcycle). People who got admin sep'd made a conscious decision not to follow the rules, perhaps thinking that they wouldn't get caught or maybe didn't realize that Peace Corps is serious about this, or maybe thought as a group they wouldn't all be sent home, which unfortunately happened in some cases.

I think that the best way to minimize the stress is just decide to follow the rules and make the right decisions.
