How have your views changed on parenting from before having a kid to after having the kid?

You know when you’re younger and you’re pissed off at your parents for something that you don’t think you should get in trouble for, then you think to yourself “I’m never going to be a jackass parent like that, I’m going to let my kids do [this and that]” . When you actually have had a child what do you think of those thoughts you once had?
