What people in the world think of you is really none of your business.

The remark urges a disciplined indifference to public opinion: other people’s judgments are outside one’s control and therefore a poor basis for self-direction. Read in light of an artist’s life, it frames reputation as a byproduct rather than a goal—something that can distract from the work itself. The line also distinguishes between constructive feedback (which can be chosen and used) and the endless, uncontrollable churn of social approval or disapproval (which cannot). Its significance lies in its practical ethic: protect attention and integrity by focusing on what you can govern—your choices, craft, and character—rather than trying to manage others’ perceptions.

2) “What people think of me is none of my business.”
