Everyone have that area where they find themselves comfortable to study or to write some stuff. I also like to write or study when i find something new or want to write down anything.
I prefer to work in calm and comfortable area so that i can get good motivation and ideas.
As i start to write something, i spontaneously gets the ideas and lines in my mind about what to write. If i writes any fiction, then i makes the images in my mind about that story.
Well this is very normal, from the point of view of one writer because he/she experiences same thing.
I prefer to write down my ideas in my home, only at that time when there is perfect quietness.
