What’s the purpose of life?

I don’t really know what I’m meant to be doing. I work so I can live in a house and I have the bonus of helping people in my job…but like is this it? Do I focus on making more money? Making more friends? It all feels a bit shallow. When I was a kid I wanted to be in history books, like do something great that people would remember me by but I don’t think I’m that smart. I don’t feel the need to have kids, there’s already far too many people and there is a lot of suffering, I wouldn’t want to pass on my possible mental illness either
