Finite Divisions
Frantic clicking and switching on the computer lead to the same behavior in life.
The hours we spend flitting constantly among task train us to treat our time and our attention as infinitely divisible commodities. On a screen, it's easy to jam more busyness into each moment, so that is exactly what we do. Eventually the mind falls into a mode of thinking, a kind of nervous rhythm that's inherently about finding new stimuli, new jobs to perform. This carries over into the rest of our lives; even when we're away from screens, it's hard for our minds to stop clicking around and come to rest.
