FACT: You are not required to give a fuck.
Contrary to popular belief, giving no fucks does not mean that you sit around all day in your sweatpants, smoking weed, and eating cereal (although, mmm...cereal). No. The hallmark of not giving a fuck is self-reliance.
Once you become self-reliant, your self-worth is not dependent on the opinions of others. A person who needs nothing from others is a person who cannot be manipulated or controlled by external forces.
And that is the ultimate power. Wouldn't you agree?
