Dostoevsky.. the legend

I have read so many authors, but no one can come near Dostoevsky. That craziness, depth of analysis and ability to make you think, these are mind boggling. This 20th century Russian , supposedly wrote for sheer love of it and partly to support his gambling addiction. Now reading his notes from underground novel. Whole novel dwells into darker psychology. He tells that he will never achieve anything [ actually in sense of materialistic world ]. Because he is too conscious. And worst part is he thinks !!! Its so true. Life is hard once you start thinking about everything and start asking questions.
