Yet 95% of the professionals persist in “doing the same thing over and over again and expecting different results.” Einstein defined this as insanity.
This fixation with ineffective approaches is costly. In the United States, work productivity losses due to violence range from $1,000,000 – $5,000,000 per victim, whether it’s homicide, suicide or mass murder. (more…)
