Insanity or a new model?

I just read this in Seth Godin’s post titled “Time for a new model?”:

The thing is, when your model doesn’t match reality (when you have trouble predicting how your investments will do, whether a sales call will resonate, whether a presentation will work, whether a new hire will work out) it’s tempting to blame reality.

What is that old adage about insanity and doing the same thing over and over?
