He was always working on something—yet at the end of the day, he had rarely accomplished any tasks to move him closer to the life he wanted.

The ___9___ is to slow down and get comfortable with being still, with contemplating what we really want and whether our actions are suitable for our goals. Many of our activities are avoidance activities: we do things to fill up the time and thus avoid having to do more difficult tasks.
