Suggested answer:

Dear Jack,

Knowing that you are addicted to online games,I’m rather worried and anxious.Thus,I’m writing to give you some advice to change the bad habit.

First of all,you should be aware of the harm of online addiction.The bad habit,if left unchecked,can lead to physical and mental problems.To change the bad habit,you’d better examine your bad habit cycle first and then replace the negative routine with something more positive.So,when you feel bored again,rather than play computer games,you can listen to some of your favourite music instead,which will make you feel relaxed.Besides,it’s impossible to break bad habits quickly.Actually,the most successful way to change is to show some discipline and repeatedly take many steps.

All in all,I do believe you have the power to build a healthy and happy life full of good habits!

Yours,

Li Hua
