Hello. I think a lot of teenagers are like this. My 19 year old son has been like this since the last few years of Primary School. Have had to practically drag him kicking and screaming through his education, even now. If it was up to him he would do **** all but lie in bed, sleep and play X Box with his mates all day. It's only because I don't give him that choice that he is doing what he's doing. Try not to stress about it too much. You are the way you are and sadly, not everyone can be highly motivated in life.
