“Yet he argued that even a tedious topic can take on a certain fascination if you make an effort to look at it afresh: "The subject must be made to show new aspects of itself; to prompt new questions; in a word, to change. From an unchanging subject the attention inevitably wanders away.”

“Because you actually might not know what activities truly engage your attention and satisfy you, he says, it can be helpful to keep a diary of what you do all day and how you feel while doing it. Then, try to do more of what's rewarding, even if it takes an effort, and less of what isn't. Where optimal experience is concerned, he says, "'I just don't have the time' often means 'I just don't have the self-discipline.”

“Your motivations--get that promotion, throw the best parties, run for public office--aren't impersonal abstractions but powerfully reflect who you are and what you focus on. An individual's goals figure prominently in the theories of personality first developed by the Harvard psychologist Henry Murray. According to his successor David McClelland, what Friedrich Nietzsche called "the will to power," which he considered the major driving force behind human behavior, is one of the three basic motivations, along with achievement and affiliation, that differentiate us as individuals.A simple experiment show show these broad emotional motivations can affect what you pay attention to or ignore on very basic levels. When they examine images of faces that express different kinds of emotion, power-oriented subjects are drawn to nonconfrontational visages, such as "surprise faces," rather than to those that suggest dominance, as "anger faces" do. In contrast, people spurred by affiliation gravitate toward friendly or joyful faces.”

“Among these temperamentally unhappy campers are "reactant" personalities, who focus on what they often wrongly perceive as others' attempts to control them. In one experiment, some of these touchy individuals were asked to think of two people they knew: a bossy sort who advocated hard work and a mellow type who preached la dolce vita. Then, one of the names was flashed before the subjects too briefly to register in their conscious awareness. Next, the subjects were given a task to perform. Those who had been exposed to the hard-driving name performed markedly worse than those exposed to the easygoing name. Even this weak, subliminal attention to an emotional cue that suggested control was enough to get their reactant backs up and cause them to act to their own disadvantage. All relationships involve give-and-take and cooperation, so a person who habitually attends to ordinary requests or suggestions like a bull to a red flag is in for big trouble in both home and workplace.”

“Whenever you squander attention on something that doesn’t put your brain through its paces and stimulate change, your mind stagnates a little and life feels dull.”

“Research shows that when they confront a potentially unpleasant situation, such as some unfriendly faces at a gathering, these extraverts are apt to shift their attention rapidly around the room and zero in on amiable or neutral visages, thus short-circuiting the distressing images before they can get stored in memory.”

“Recently, the search for what he calls "the splinters that make up different attention problems" has taken Castellanos in a new direction. First, he explains that your brain is far less concerned with your brilliant ideas or searing emotions than with its own internal "gyroscopic busyness," which consumes 65 percent of its total energy. Every fifty seconds, its activity fluctuates, causing what he calls a "brownout." No one knows the purpose of these neurological events, but Castellanos has a thesis: the clockwork pulses enable the brain's circuits to stay "logged on" and available to communicate with one another, even when they're not being used. "Imagine you're a cabdriver on your day off," Castellanos says. "You don't need to use your workday circuits on a Sunday, but to keep those channels open, your brain sends a ping through them every minute or so. The fluctuations are the brain's investment in maintaining its circuits online.”
