That's why I felt my situation and my wife's differed. Mine was simple because there wasn't an underlying pile of complexity. Her underlying "addiction" and etc are noteworthy items in her list of things she needs to do. It's simple if you ignore the problems, but if she wants to actually implement that simple instruction she needs to figure out the little details that affect her.
So yes, it is simple if we're not talking about her situation with context and reality. Mine is simple in all contexts, in my opinion.
Smoking is a good example imo on where our opinions differ. Smoking is super far simple in my mind, because many people can't just stop smoking (or rather, lack the willpower). So they need additional data, the simple instruction was.. imo, not so simple.
