One thing I strongly impress upon the young people that I talk with is that they were born with everything they need to succeed in life. God gave them the tools, the instincts, the talents...each unique to who they are and who they were meant in this life. No one is "stamped" with a note "please bombard this body with drugs and alcohol in order to achieve ultimate joy". They each need to explore and develop those talents and gifts by looking inside and putting in the hard work of growing up.
Just as important is that parents understand that they need to help their children along in this process; they cannot leave their young people to do this on their own. The animal kingdom does not even do this... they help their young learn the skills they need in order to just survive. Teaching our young people to merely survive just isn't enough. It's important to nuture youth, to show them love, affection and the art of discipline in order for them to find their way to becoming productive citizens- drug free citizens. This first comes from teaching them how to be part of a family unit. They need to know and understand their role, importance and responsibility within their family. Yes, responsibility is part of equation.
When we leave children to their own devices they are often left floundering aimlessly following whatever or whomever will allow them to be part of their crowd.
