I like the concept of this from 43Folders - “Cancel Something“:

The important thing is to find at least one thing that’s become a noise generator, time sink, or attention sieve, and be rid of it. The hack isn’t how big a change it brings in your life — remember these are modest changes — it just matters that you mindfully elect to turn something off for a little while. That little scrap of time or attention you gain back is then well and truly your own.

Worth a read.
