How relevant is Freelancer's Bible by Sara Horowitz to new freelancers?

[Btaliat]

There are many books that have been written by different authors on freelancing, but the one that most people always recommend is Freelancer's Bible by Sara Horowitz. I don't know how relevant the book is, especially during this time that you can get much information about freelancing on different platforms. Have you read it before? Is it a must that a freelancer, especially new one, read it before starting freelancing? Share your opinion about this in the comment section
