I like Philip Larkins poem below.
But I don't agree with the last line.
But I do understand that how you're brought up and what you experience can impact who and how you are, and can then affect your kids, and theirs.
I can be anxious, I have a hurry up and be perfect driver, I regularly 'push' that on my kids, I'm trying not to, and being aware is the first step to taking different action.
This is a good article http://www.thebookoflife.org/how-a-messed-up-childhood-affects-you-in-adulthood/
Even if you don't want to change yourself, for yourself, you might want to for your kids.
