So concerned with what others say?

Questioner: Sir, my family keeps asking why I am never interested in doing general stuff. They keep asking what I want to do, and where I want to go. My reply to them always is, “I do not know.” I don’t want to do what I am doing, that I know. But I do not know what I want to do. This disturbs me a lot.

How can I get the concern of others get out of my mind?
