Engineers your environment to make desired behavior default and undesired behavior expensive.

For a behavior you want more of: name the three biggest points of friction between you and doing it. Remove them.

For a behavior you want less of: name the three smallest points of friction. Add them. Move the phone to another room. Uninstall the app. Freeze the card.

Your environment either pays you dividends or taxes you. It is never neutral.

RUNS: 20 minutes. Repeat when behavior slips.

From The Operator’s Edge, Principle #5.
