What does this say?
There's a time for consuming and a time for producing.
Those that will thrive in the 21st century are those who can toggle between the rapid digital pace yet still create little pockets of attention for themselves to write a blog post or read a book. Single-tasking intends to go deeper.
Attention is scarce. But the abundance of information is also helpful. It feeds you with ideas and makes you realize there's so much to learn and so much more to do. But without moments, even half-hour, of single-tasking it's almost impossible to obtain the deep insight you're looking for. For that, you need to chew on something for a while.
The ability to weave in and out of pockets of concentration, to get some stimulation and then come back to your work is the key, per say.
