"فن اللامبالاة" (The Subtle Art of Not Giving a F*ck) is a book about personal development, written by American author and blogger Mark Manson. This Android application is a book summary that includes text and images from the original book. The book was originally published in English in 2016 and was translated into Arabic in 2018.

The main idea behind "فن اللامبالاة" is that humans do not necessarily have to be positive all the time, and true happiness comes from facing reality and accepting its positives and negatives. Manson starts the book with the shocking truth about most self-help books and how they deceive us by making us believe that we can change everything around us with the power of our minds. He emphasizes the importance of knowing our limits and weaknesses to walk on the right path towards our real goals, not the ones imposed by our surroundings.
