when I decide to write something , its usually based on Impulse . I start to ponder over the issue , the story line and the characters to make my first "mind draft" . But after a chat with my friend and listening to advice of screen writers I have been confused and skeptic over the methodology suggested . Writers suggest to read books related to the issues , documentaries , news articles and anything that may sound similar to your theme. But I certainly have a problem with this advise, according to me its like picking words from different sources and then arranging them to make it logical . What about the purity of my Idea, it just got corrupted .
