“In a variation on James's recipe for interesting experience--the familiar leavened by the novel--Hobbs's "art of choosing difficulties" requires selecting projects that are "just manageable." If an activity is too easy, you lose focus and get bored. If it's too hard, you become anxious, overwhelmed, and unable to concentrate. Tellingly, one group is distinguished by its zeal for the kind of work that requires you to give it all you've got: high achievers particularly relish taking on risky projects that have only a 50/50 chance of success.”

“Over time, a commitment to challenging, focused work and leisure produces not only better daily experience, but also a more complex, interesting person: the long-range benefit of the focused life. As Hobbs put it, the secret of fulfillment is "to choose trouble for oneself in the direction of what one would like to become.”

“Temperamentally anxious people can have a hard time staying motivated, period, because their intense focus on their worries distracts them from their goals.”

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.”

“Arguably the mos intriguing characteristic assessed by the Multidimensional Personality Questionnaire (MPQ), a widely used test developed by the University of Minnesota's eminent psychologist Auke Tellegen, is "absorption," which describes a particular style of focusing. If you get a high score in this trait, you're naturally inclined toward what he calls a "respondent" or "experiential" way of focusing.”

“If you really want to focus on something, says Castellanos, the optimum amount of time to spend on it is ninety minutes. "Then change tasks. And watch out for interruptions once you're really concentrating, because it will take you twenty minutes to recover.”

“Once out of your cradle, you don't focus on the world in the abstract, perceiving things for the first time, but in synchrony with your accumulated knowledge, which enriches and helps define your experience, as well as ensuring its uniqueness.”
