FICTITIOUS CONVERSATION WITH PROBLEM RESOLUTION

—So, Professor, doesn't it worry you the way children nowadays spend so much time in electronic devices? Take my kid for example. It cannot be right!
—Well, that depends, Is he responsible with his academic duties simultaneously?
—No way. He does not only spend his whole leisure time sticked to a screen, but I also have to almost beg him to attend his academic duties for being so absorbed in the devices.
—I see. Does he have the same attitude towards other activities or just school?
—Oh, with everything else. He is always quite reluctant to do excercise, and when I take him, he is apathetic the whole class.
—Well, that can be pretty unhealthy, then.
—What shall I do?
—Well, let's see. What have you tried?
—I had him subscribed to sport clases and I make him come with me to work so he can help me instead of playing videogames and I try to keep him busy also at home, but he just does not quit the habit.
—Those measures are sounding to me that you are rather a little bit rigid with your child. Were all those activities you take him to chose by him?
—Well, no. I chose them. But that wouldn't make a difference. Right?
—You see, if you want your child to do something else, you need to have the aim of motivating him by letting him choose his alternatives. Otherwise, he will not develop the habit of doing something else. Next time you approach him to talk about alternative activities, you should try making him feel the freedom of choosing whatever he wants. 
—What if what he wants is still not as productive as it should be? What if he does not want excercise at all?That's why I'm choosing his activities!
—That is a little risk that should be taken at the beginning, but if you want him to do other activities willingly, it is the best way to start. Once you observe he is giving in, you could carefully suggest additional types of activities.
—I had never seen it that way. I wish he could suddenly just want to do what is best for him, but you are right. That is not possible. I have to make sure he is happy with his additional activities. After all, it's his wellbeing that matters to me, right?
