Like it or not your
youth will look to you for moral guidance.  You cannot, like the
celebrities, try to pretend that your actions and life are not
anyone's business and you have no intention of being a “role
model.”  Not only are you (and they) role models, you have signed
on for that job!   So the youth around you are watching, mostly
unconsciously, your every move trying to learn what it means to be a
“Christian adult.”  (remember the anti-smoking ads?) So, what are
you teaching them?  
- 
Periodically
 we need to stop and look at our actions and interactions to make
 sure we are teaching them what we intend to teach them 
- 
If
 we see behaviors in the youth that bother us, we need to first look
 at ourselves to make sure we haven't taught them that. 
- 
When
 teaching a lesson or preaching, we need to see how much if applies
 to our own lives.  
  
- 
If
 the concern is a difficult one (“I need to be less sarcastic”)
 at least admit that it is a problem that you are trying to overcome.
   This, in itself is an important lesson for them to learn. 
- 
Never
 make excuses when you slip up. 
- 
As
 I have said in other posts, we may have to adhere to a code that we
 do not consider necessary – specially for an adult, but if it is
 something we don't want to our youth to emulate, we may have adhere
 to it – for their sake.
