Caring less is not about apathy or a lack of empathy for others. Apathy is the refusal to care – it’s a sign of an absence of empathy – and that’s a ruinous habit that encourages us to disconnect with the world and be an isolated person.
Caring less, or saying that you “don’t care” about something, can be about one’s acceptance of reality and things that you cannot influence or change, and then not worrying about such things. It’s about letting the little stuff slide.
