R < D × V × F. The R is for “resistance to change.” In order for change to happen, the product of the other three variables has to be larger than the resistance. The D stands for “dissatisfaction,” meaning you need to be aware of the cost of your present behavior. The V stands for “vision,” meaning you need to see the benefit of new behavior and believe that the result will be worth the effort, and the F stands for “first steps,” meaning you believe you can acquire new skills that make change easier.
