<human>: Give me a shortened version of the text

I am currently 21 years old, but I have been thinking about this question for quite a while now.  I have known people who enjoy the idea of a child, but once they have a child they have no idea on how to raise it.  And when they become older and more conscious of their own opinions towards certain topics the question is "How was a parent really get through to a child?"  I have seen so many kids who end up going down a bad path, despite what their parents warn them about or try to help them with, they just won't listen. Even when I was younger I often found myself fighting with my parents about things I thought was right from my point of view, however ended up being very wrong after I experienced it myself.  

One day I found myself spending a really long time contemplating the idea on how to best approach my children in the future, if I end up having any. So I created a set of videos of myself explaining certain topics directed to my children.  Each topic is roughly centered around different adolescent benchmarks, for example in some videos I discuss what to expect when you first enter High School and what my preconceived notions of High School were, another video discusses bullying, things I wish I would have done in high school, personal mistakes I have made (financially, in relationships, and so on).  The idea behind this was mainly driven by the idea that if I could approach my kids from a younger perspective, that it would have a greater impact on them instead of the old cliche "When I was your age..." line.  

Now the question I'm interested in is how do other parents effectively reach their kids and prevent them from making costly mistakes?
<bot>: I made a set of videos for my children now that I am young (21 yrs old) so that they can listen to what I say and we can relate.
