What I didn't do

Hello, I'm having one of those moments when you just need to express it somehow.  It doesn't really matter to whom or if it's even read.  But having it out here makes me feel a little better and somehow not so lonely. Once again, I've been schooled on my parenting practices, or lack thereof. Here is my big question.  How do you go back and instill in your children confidence and practicality? How do you make your adult children understand that .....I did it all wrong.  I'm sorry, please learn from my mistakes. I'm tired and needing to sleep but I will let you know if anything marvelous comes of this.
