What is the main conflict in The Book of Disquiet by Fernando Pessoa?

Fernando Pessoa describes his work "The Book of Disquiet" as being an autobiography lacking facts. It is written by character Senhor Soares, who is assumed to be an alter ego for Pessoa. Pessoa's book does give few concrete facts about the writer or the world of the writer. The book is rich in describing the inner workings of the mind and soul of the author. Through his book, Soares explores the reasons why he writes and why he writes as he does, as well as an ailment that often affects him which he terms "tedium."
