Whenever I want to study, I think about stopping playing with my mobile phone after 10 minutes of playing, but I always procrastinate, and then I play with my mobile phone until I go to sleep, without the energy to complete the task of the day, and then postpone it until the next day... 
however, the most impactful changes must be within you...focus is the most appropriate thing to leave your less productive thing. Your parents must be very difficult to change you if you don't want to change yourself.
