Desire to write

I was reading an article by Edward said, who was a prominent writer and a Professor at Columbia University. While going through the article I have found something very stunning. Perhaps that was the answer to one of my questions which I have asked myself in a previous post. Said gave the reference of Joseph Conrad who said in Nostromo, a book written by him, that a desire lurks in every heart to write down once and for all a true account of what happened. This is the reason why I, sometimes think that I should write down each and every event which is happening to me or had happened to me.
