This from an interview with Linda Stone:

The people I spoke with who worked in office jobs typically said they managed their time. Many of them had taken time management classes and had things carefully mapped out during the day. This included everything from how many minutes were spent in meetings, on email, on the phone, and with their children. Almost everyone who said they managed their time reported being overwhelmed and feeling burnt out.

When people reported managing their attention, they reported more flow states. It was really interesting. The people who were most likely to say they manage their attention –- artists, CEOs and surgeons — actually described a process of managing a combination of time and attention.

Many executives and CEOs said that if they didn’t manage their attention, they found they would deal with the little things and miss strategic opportunities. They said this was something they had to learn when they moved into the CEO position.
