Shifting perspective, like shifting our thoughts, is largely a matter of cues. In order to choose, we must become aware of the cues that we respond to. These may include habits from childhood, our education, and all the ways we are influenced by our experience and training. In conversation, in meetings, in making our plans for the day or for the year, and in all of our decisions, we are responding to cues.

Escher's picture shows that although we are powerfully affected by cues, we do have choices. We can see the picture as either convex or concave, or both.

In order to concentrate on the perspective, the architecture, we may have to learn to accommodate contradictory cues, perceptions, or signals. The first step may be learning to ignore the trumpeter or the flag.

The need to change perceptions and thinking is not yet accepted by most institutions, political leaders, corporations, nonprofits (NGOs), or universities. Most continue to formulate policies and do research as if sustainability or better living can be achieved without changing perception and thinking. But our best efforts and hard work, unless they are guided by a recognition of wholes rather than a focus on parts, will only dig deeper the pit we are in.

What follows is a roadmap, based on observation and reporting about people who are having considerable success in dealing with seemingly intractable problems. These successes require no expensive technology or specialized knowledge, but are within reach of those who choose to perceive, think, and act differently.
