The Power of Negative Thinking

 

It's been said that I believe in the power of positive thinking. 
In fact, I believe in the power of negative thinking. 
I happen to be very conservative in business. 
 I always go into the deal anticipating the worst. 
If you plan for the worst - if you can live with the worst -
the good will always take care of itself.
