The definition of insanity is doing the same thing over and over and expecting different results.  This truth can be said of anything that happens or of that which you do.
On the other hand, if doing the same thing repeatedly nets you success, then by all means, carry on…unless, what you do is at a cost to someone else.
Of course, what you do that appears successful on the surface may not really be so if someone enables that “success”.
Its one thing to have a silent partner but even a silent partner receives a portion of the spoils of success. 
Consider if you are truly successful or are you simply being enabled at someone else’s expense. Consider if you are acting in an insane manner by doing something again and again with the expectation of different results.
Know when to say when and find your own route in life.
