“Negative thinking is something we all do. The difference between the
person who is primarily optimistic and the person who is primarily
pessimistic is that the optimist learns to become a good debater. Once
you become thoroughly aware of the effectiveness of optimism in your
life, you can learn to debate your pessimistic thoughts.”
