The Subtle Art of Not Giving a Fuck: A Counterintuitive Approach to Living a Good Life by Mark Manson

Contrary to what the title might initially suggest, the book isn't about becoming indifferent or apathetic. Instead, it argues that a fulfilling life comes not from trying to eliminate problems or feel good all the time, but from choosing what problems you are willing to engage with and what you genuinely care about (i.e., what is truly fuckworthy). It's about strategically allocating your limited fucks to things that align with your core values.
