Some family cycles stop because one person got tired of repeating them. Be that person.

Patterns run through families because they get learned before anyone can evaluate them, not because anybody chose them. Seeing one clearly is the hard part, and you can only see it from inside. Once it is visible, it stops being automatic, which is where the possibility of doing something different starts.

Name one pattern you have decided not to carry forward, specifically enough that you would recognize it happening. Watch for the moments you feel the pull, usually when you are tired or angry. And get help with the heavy ones, because nobody is meant to do this entirely alone.
