Training every spare moment of time.

[b3N0m]

Hi. I am not sure if this is the right place to post but I am looking for some advice on how to stay focused for long periods of time during soccer/ football training. I want to become a professional football player and it is my passion in life. I already have come a long way and play for an international academy. But what I am asking for is advice on how to stay focused when I train alone. On weekends and school holidays I will try to train at least 6 hours every day alone. But I find it hard sometimes to train for more than 2 hours at a time before I have to have a break and then go back out to train and finish my 6 hours for the day. I would just like some advice on how to train all day everyday (except for school days of course because I am at school.)I find it hard to wake up early but I need to be getting around 2 or 3 hours of training in before school before going to school and playing football with friends for an hour during recess and lunch and then going to the academy to train another 1 and a half hours. But the main reason I am posting this is to get advice on how to stay fully focused and train for long periods of time. I know that I definitely can become professional but I want more than that I want to become a great player.
Any advice will be appreciated thanks. :)
