I guess it mean many things to many different people. To me it just means follow directions.
I never liked the "Keep It simple Stupid" slogan. I'm not stupid and neither are you. In fact there isn't anything stupid about the program. The only thing stupid are silly-ass slogans like this that people use for an excuse to stay sick. Kind of like what Carol said "Keep it soft & shallow," now I kinda like that one.
