This is a good and balanced reply. My brother was much more rebellious than me when he was younger. Not as crazy as your first post, but crazy enough for our relatively conservative family. When he got married and had kids later, he is -- to my great surprise -- a very strict, conservative parent. He has his daughters on the straight and narrow path. Sometimes I wonder will they go crazy as soon as they got to uni (move away from home). I saw more than a few crack during my first year of uni, living in dorms. You can probably find some books or blogs that people have written about their own journey as a parent, especially when they had a rocky start in life as an adult.

I am not a parent, but I have observed that the best style of parents adapt to the natural personality of each child. For example, I was very contientious from early childhood (I assume that part was genetic), and my brother was exactly the opposite. My parents really had to work with him to get him to take school seriously. Fortunately, he has a naturally high IQ, so it wasn't so hard for him.
