The Art of Unfuckdness: "The Subtle Art of Not Giving a F*ck" by Mark Manson

The Subtle Art of Not Giving a F*ck: A Counterintuitive Approach to Living a Good Life - Mark Manson

Ah, that reminds me of an old joke: Two guys meet their former colleague at a street corner and one of them says: “ Joe, we have a good laugh every time we talk about the day you told the boss you were fed up of daily project meetings and unmet milestones”

It is an invariable fact of life that the vast majority of people that go around declaring to the world at large that they don't give a fig about others opinions actually care more about them than those that stay quiet on the issue.

The author has just taken the title of a best-selling book (“The Life-Changing Magic of Tidying Up”, and chosen an alternative that will stand out in the bookshop and encourage newspapers to run excerpts that look good in bookshops. I think it's an attempt to piggyback on the success of Marie Kondo's book by being "inspired" by the title and hoping people will pay money without looking too hard at the contents of the book.
