I have been hearing this saying for some time now and wondering what does it mean.
Doing something over and over again and expecting different results turns out to be a job. We were instilled in this rule of keep doing something and you will get better at it.
A doctor does not do anything, he practices for years at his craft while he perfects his skills.
One the other hand, a criminal always gets caught, because he does the same way all the time.
But seriously, if I keep doing something, whether it is correct or not, I would learn something and/or change the way things were being done.
Why does in marketing seems to be different? Does doing the same thing over and over expecting different results work is marketing?
