I sense a lot of projection from this post. Sorry you didn’t have the same stable household I did. See how easy it is to make assumptions about someone you don’t know?
On the one hand, you say those who become successful in spite of their dysfunctional homes, did it due to self determination. Ergo, according to your logic, parenting is ineffective because a child’s fate is predetermined?
Make it make sense.
I am the person I am today because of the principles and hard work ethic my parents instilled in me. My parents have never had to pat themselves on the back for their parenting, I’ll happily pat it for them. They gave me the tools and I built from that.
I will always be indebted to my parents because I see so many shytty ones. I won the lottery having my mom and dad and I’ll never be ashamed to say it, despite what self esteem issues you assume I have.
