Ask HN: How to be okay with having an average intelligence?

Some people change the world, some people see and solve problems majority can't and need to study to understand. How can you be okay knowing you'll never be one of those people that actually leave the mark? How can you be okay with having a wife, a child or two, raising them, but knowing all of you are just average? How can you ever be okay unless you know and are proved to be a genius?
