People respond to a positive proposition with energy that’s optimistic and sustainable. That is, people will strive for something compelling even, or especially, if it’s challenging. On the other hand, identifying something wrong or objectionable and fighting against what is, gets meager results compared to pursuing a desired outcome. Analysis or critique of the current state can be useful, but a problem focus fills up the available mental and emotional space leaving little room for a positive alternative. By contrast, the desired outcome makes the challenge of now minor relative to the promise of the future.
