due to day dreaming unable to concentrate in classroom

Yes, this is definitely the work of a Devil. There are many times when I've daydreamed off to China's Great wall or John F. Kennedy's resting place. I believe it gets me sadder and more dull every time I practice it. Theres not much that can assure me I will stop this really bad behavior. I've always thought it was lack of sleep that was contributing to it, but as I learned more it could be to many different problems an individual has. Focus, energy and forward thinking will limit such day dreaming episodes.
