Parents or grandparents should try to educate the children by telling them various stories where they get good information about the realities of life. How Rama suffered in obeying the words if his father. How the king's son got converted to Gautam Buddha and what made him change like this etc. should be described to them so that they will understand the realities of life. But these days parents are not having much time to spend with their children. They will be busy and the children will be busy in passing time with mobiles.
"Life is easier when you enjoy what you do"
Believe in the existence of God the super power.
