The Subtle Art of Not Giving a F*ck — Mark Manson (2016)

Mark Manson's deliberately provocative counterintuitive self-help book (10 million copies sold) argues that most self-help's emphasis on positive thinking and optimism is counterproductive, and that a meaningful life requires consciously choosing what to care about — accepting negative experiences as inevitable and finding meaning in difficulty rather than seeking its elimination. Its rejection of toxic positivity struck a chord with a generation sceptical of conventional self-help.
