What is what other people think of you is none of your business?

The concept that what other people think of you is none of your business is rooted in the idea that focusing on others' opinions can be detrimental to your own well-being. It essentially means that you should not base your self-worth or decisions on the approval or judgment of others.

Some believe that this perspective can empower individuals to live authentically and prioritize their own values and beliefs. It can also help to reduce feelings of insecurity and comparison, as seeking validation from others is not the main goal.

Ultimately, it is important to remember that everyone has their own perspective and biases, and their opinions are often based on their own experiences and beliefs. It is up to you to determine your own worth and identity, rather than seeking it from external sources.
