Dear Welcome to HCM We understand your concerns I went through your details. I suggest you not to worry much. From the given description, I just can conclude you that you have concentration problem. You should have mentioned your age and other medical conditions. I assume that you are a teenager or an young adult. Concentration cannot be lost on single subjects. If you are able to see a block buster movie continuously, then you have good concentration level. If you are able to play a video game, then you have good concentration. Then what could be reason for your low concentration in reading your education related books. Lack of interest, of course. The books are boring. You do not have the passion with your subject. You are not alone. Millions of youth around the world are on the same path. Once you are able to cultivate interest, in the study subjects, the wandering stops. If you require more of my help in this aspect, Please post a direct question to me in this website. Make sure that you include every minute details possible. I shall prescribe some psychotherapy techniques which should help you cure your condition further. Hope this answers your query. Available for further clarifications. Good luck.
