Positive thinking can do wonders for your attitude. But it won’t make a difference in achieving your goals. Instead of just thinking positively (and vaguely) about what you want to accomplish, use mental imagery to ensure your success. These five tips show how to get the most from mental imagery.

The power of mental imagery

I first became aware of the power of mental imagery in 1976 when the USSR stunned the world by walking away with most of the Olympic gold medals. At first people suspected the athletes had been taking drugs, but it turned out that was not the case. They had discovered that when athletes supplemented their practice through visualization, not only were they better prepared to compete in a variety of conditions, but their motivation and self-confidence also increased.

As a result, a new field called “sports psychology” emerged. Today mental imagery is an integral part of training for Olympic athletes. According to The New York Times article “Olympians Use Mental Imagery in Training,” the United States brought nine sports psychologists to Sochi in 2014.

There’s a lot of anxiety out there about robots gobbling up our jobs. One oft-cited Oxford University study predicts that up to 47 percent of U.S. jobs are vulnerable to automation. Other research suggests the share is much lower. But while the exact numbers may be debated, there’s little question that technology is changing quickly and reconfiguring the tasks many of us do.

As the labor market demands different and evolving skills, what does that mean for higher education? Is a four-year degree still the best way to obtain a well-paying job? And what subjects and experiences do students need exposure to while they’re in college?

Hearing aids, dental crowns, and limb prosthetics are some of the medical devices that can now be digitally designed and customized for individual patients, thanks to 3D printing. However, these devices are typically designed to replace or support bones and other rigid parts of the body, and are often printed from solid, relatively inflexible material.

Now MIT engineers have designed pliable, 3D-printed mesh materials whose flexibility and toughness they can tune to emulate and support softer tissues such as muscles and tendons. They can tailor the intricate structures in each mesh, and they envision the tough yet stretchy fabric-like material being used as personalized, wearable supports, including ankle or knee braces, and even implantable devices, such as hernia meshes, that better match to a person’s body.

Whatever the process or type of data collected, all data display variation. This is also true in software development. Any measure or parameter of interest to our business will vary from time period to time period, e.g., number of incidents per week or month, time taken in resolving incidents, number of tickets encountered in a production support environment per month, and defect density in code.

Understanding variation is about being able to describe the behavior of processes or systems over time. This variation can be stable, predictable, and routine, or unstable, unpredictable, and exceptional. Being able to distinguish between stable or common-cause variation, and unstable or special-cause variation, helps us to decide the type of action needed to improve the process. The control chart, developed by Walter Shewhart, is the tool that enables us to do so.

For decades, relatively easy access to space and the big profits to go with it have dangled elusively just over the horizon. With a little more R&D money and a few more advances in the technology, the thinking went, space would be ours.

Are we there yet? More than a few signs are pointing in the direction of a robust, varied space age of viable commercialization—as well as more audacious goals than we’ve seen in generations.

On the practical side, advances in reusable rockets, lowered per-launch costs, and miniaturization of satellites are opening up business opportunities well beyond aerospace and defense, and into IT hardware and telecom, according to Morgan Stanley. The global space industry is expected to generate revenue of $1.1 trillion or more in 2040, up from the current $350 billion, according to a recent report by the firm.

On the dream side, Amazon founder Jeff Bezos recently outlined a long-term vision for putting a trillion people in space colonies with one small step coming soon: an infrastructure starting with lunar lander Blue Moon. “We are going to build a road to space,” Bezos said at a May unveiling of his plans, “and then amazing things will happen.”
