The first two steps are: 1. Deciding what you don’t give a fuck about. 2. Not giving a fuck about those things.
Does it improve your life to worry about this issue, or does it simply make you feel depleted?
Too often, we base our decisions on what we *should* do, perpetuating the cycle of obligation and resentment.
The beauty of not giving a fuck is that it allows you to reserve your time, energy, and mental space for the things that actually matter.
Before Knight's manifesto, saying "no" was often considered selfish; now it's recognized as essential self-preservation.

Imagine having a magic button that instantly removes all the unnecessary stress, obligations, and anxiety from your life. That's essentially what Sarah Knight offers in her refreshingly irreverent guide to mental decluttering. While Marie Kondo taught us to tidy our physical spaces, Knight introduces something even more powerful: permission to tidy our mental space by stopping the endless cycle of giving a f*ck about things that don't actually matter to us. The NotSorry Method consists of two deceptively simple steps: deciding what you don't give a f*ck about, and then not giving a f*ck about those things - without being a jerk about it. The method emerged from Knight's own journey as a "born f*ck-giver" - an overachieving perfectionist who said yes to everything out of obligation, guilt, or fear of judgment. Everything changed when she met Jeff, a man who seemed remarkably content because he simply didn't do things he didn't want to do. He saved his limited supply of f*cks only for what truly mattered: his children, golf, and Jeopardy! This encounter sparked the realization that contentment wasn't about doing more, but about doing what matters. Think of your f*cks as a finite resource - like money in a bank account. Every time you say yes to something you don't actually care about, you're making a withdrawal. Give too many, and you'll hit zero, leaving you stressed and depleted. The goal isn't to stop caring altogether, but to redistribute your f*cks to areas that genuinely deserve them.
