Eigentlich hat man es ja schon oft genug gehört, aber so richtig im Leben und in der Lebenspraxis ist es wohl kaum angekommen — die Zerstreuungen und Ablenkungen der modernen Welt machen uns unproduktiv und mürbe.

Ein interessanter NYTimes-Artikel macht diesen Punkt noch einmal in aller Deutlichkeit, und hat auch einen praktikablen praktischen Ratschlag:

“Multitasking is a myth,” Ms. Gallagher said. “You cannot do two things at once. The mechanism of attention is selection: it’s either this or it’s that.” […]

She recommends starting your work day concentrating on your most important task for 90 minutes. At that point your prefrontal cortex probably needs a rest, and you can answer e-mail, return phone calls and sip caffeine (which does help attention) before focusing again. But until that first break, don’t get distracted by anything else, because it can take the brain 20 minutes to do the equivalent of rebooting after an interruption.

Außerdem noch eine kleine philosophische Ausführung, motivierend und ängstigend zugleich:

She points to calculations that the typical person’s brain can process 173 billion bits of information over the course of a lifetime.

“People don’t understand that attention is a finite resource, like money,” she said. “Do you want to invest your cognitive cash on endless Twittering or Net surfing or couch potatoing? You’re constantly making choices, and your choices determine your experience, just as William James said.”

ARGHH! JA! Ich werde mich bemühen!
