You do not need a total reinvention. You need a small behavior that fits your real week and a system for returning when you miss.
Choose one outcome
Name the change you want, then identify the smallest repeatable action that can support it.
Design the cue
Attach the action to a time, place, or existing routine you can reliably notice.
Lower the starting cost
Define a minimum version you can complete on a difficult day.
Review weekly
Look for friction and adjust the system instead of treating one miss as failure.
