Probably the most influential thought that influences how I act as a parent: The trauma stops with me. All the shit my parents dumped on me, that they got dumped on them by their parents it does not get passed on.
I agree that there is "generational commitment" but there's also things that you as a guardian/parent/whatever can actually do (if you are willing to work on yourself). "Generational commitment" makes it sound so big and hard (and it is hard) but a lot of the time it's just you and your partner making a decision.
You can't fix all the issues in the world but so much internalized pain can just stop (at least for your kids).
