Here's why people with shitty backgrounds have to struggle so hard to become doctors, lawyers, etc. The resources required to better yourself, educate yourself, etc. are huge. If you're always fighting upheaval, there's nothing left. You're just surviving. People thrive when they create, contribute and add to society but who has the resources to give in survival mode?
Also, when used to chaos, more is chosen. Partners may not be stable or healthy -- stormchasers are attracted to eachother.
"Stop choosing storms" good friends advise. "Let the storms inside settle and then you can rebuild in the quiet aftermath." But it's comforting, on some level, to be in the presence of someone who also understands the darkness.
This is why it is so important to invest in our children so they grow up loved and supported, happy people who give to society instead of struggling with their demons into adulthood like me.
