Well here are some facts about my friend. He works in the fambiz but he also has his own business on the side that can afford him to buy a car, rent a condo etc.. In short he would be able to survive in the world but the luxurious standards of living that he is used to would not be the same once he moves out.
Last time I talked with him he mentioned that he already told his parents about moving out but they simply refused to and got really angry with him and threatened him with stuffs that if he decided to leave he would be cut off the family tree. In short they are burning the bridges with him permanently if he would leave home.This is a serious thing so I advised him to rethink things as not to jeopardized his future.
Another thing is his dad connives with his mom so its 2 heads against one.

To Jun Pekto: What exactly have you learned by living alone. maybe you can share some specific details and examples point for point so i can impart them to my friend. Since I havent experience that yet I wouldnt be able to give the right advice that my friend needs at this point of his life.
