Steven King is well known as one of the greatest authors alive

Your argument would be more persuasive if you knew how to spell his name :)

He has a book On Writing that is very, very good. He goes through his writing process, discusses other authors, gives advice of the trade, etc. He openly admits he's merely okay/good at writing and that there's eons of better authors than him. He is being humble, but he's not the greatest writer alive by any means. He talks a lot about luck, name recognition, etc. that continue to propel him, and other shit ass authors, ahead.

The Dark Tower series is fantastic.

Dark Tower rules. I still think Complete/Uncut The Stand is, bar none, the best shit he's ever written without a doubt. I haven't got to Fairy Tale yet tho.
