This is from the February 2018 Oprah Magazine in which Oprah interviewed RuPaul:
Oprah asks RuPaul: What do you think your true purpose on earth is?
RuPaul answers: I was gonna say something unselfish, but actually I think it starts with me. The first thing is for me to experience this life and enjoy it. And if I enjoy it, I could possibly share that with other people.
Oprah responds: That’s one of the best answers I’ve heard. So many people wonder, “What’s my higher purpose?” Your purpose is to be, and to experience life on this planet in its fullness. And if you choose to do something else, that’s okay. What we’re all actually seeking is the truest expression of ourselves.
