You put a strong password on your phone and none on your mind. Guard what gets in.

You are careful about access to your accounts and generally indiscriminate about access to your attention. Whatever you read, watch and listen to goes in without a check, sets your mood, and quietly supplies the assumptions you then think with. The cost is not obvious because nothing is ever visibly stolen.

Decide one thing you will not let in during the first hour of the day, and hold that line. Notice what leaves you agitated for no return and stop opening it. This is not about purity, only about giving your inputs the care you already give your accounts.
