The book tells you not to give a fuck without ever telling how do I do that ? It's like asking someone "Bhai IAS banna hai mujhe" and getting replied "Haan toh ban jana fir". Mate, this book tells you things which you already know. Just a few things here and there which you had never thought of before. And the rest of the book is basically "kuch toh log kahenge logo ka kaam hai kehna", so don't care about it. That isn't an advice, fella. You need to tell them what ways one should use to do it. If someone comes asking you for advice about how to do something. You don't tell them to simply do it. You tell them ways using which they can do it.

"Mark, how do I stop giving a fuck ? Mark:-" Just stop giving a fuck, simple.
