how tech companies encourage behavioral addiction: intermittent positive reinforcement and the drive for social approval. - Cal Newport

As Ericsson explains, “Most individuals who start as active professionals… change their behavior and increase their performance for a limited time until they reach an acceptable level. Beyond this point, however, further improvements appear to be unpredictable and the number of years of work… is a poor predictor of attained performance.” Put another way, if you just show up and work hard, you’ll soon hit a performance plateau beyond which you fail to get any better.

in 90 percent of your daily life, the presence of a cell phone either doesn’t matter or makes things only slightly more convenient. They’re useful, but it’s hyperbolic to believe its ubiquitous presence is vital.

Also as in natural settings, in workplaces without well-defined processes, energy minimization becomes prioritized. This is fundamental human nature: if there’s no structure surrounding how hard efforts are coordinated, we default to our instinct to not expend any more energy than is necessary. Most of us are guilty of acting on this instinct when given a chance. An email arrives that informally represents a new responsibility for you to manage; because there’s no formal process in place to assign the work or track its progress, you seek instead the easiest way to get the responsibility off your plate — even if just temporarily — so you send a quick reply asking for an ambiguous clarification. Thus unfolds a game of obligation hot potato, as messages bounce around, each temporarily shifting responsibility from one inbox to another, until a deadline or irate boss finally stops the music, leading to a last-minute scramble to churn out a barely acceptable result. This, too, is obviously a terribly inefficient way to get work done.
