Ravi Zacharias said this quote

Work hard at keeping in tune with the way your children think. Your efforts may not always bring the desired result, but we must do our part. Keep close contact with them. Teach them with regularity, both by word and by deed. Love them and let them know you care for them because of who they are and not for anything else. Answer their questions with candor and thoughtfulness. Do not ignore their struggles. Deal with their difficulties, and spare them a cynical attitude. Stay tuned in to their struggles. Most of us learn the hard way that our children were in a very different world in their own thoughts than we realized.
