A philosophy of technology use in which you focus your online time in a small number of carefully selected and optimized activities that strongly support things you value, and then happily miss out on everything else.
.
…consider the technology optional unless its temporary removal would harm or significantly disrupt the daily operation of your professional or personal life.
.
To allow an optional technology back into your life at the end of the digital declutter, it must:
1) Serve something you deeply value (offering some benefit is not enough)
2) Be the best use technology to serve this value (if it’s not, replace it with something better)
3) Have a role in your life that is constrained with a standard operating procedure that specifies when and how you use it.
