Different things are important to different people. I don't think there is any set right or wrong way to live our lives and I don't think there is really any set of experiences that our life won't be complete without. It's up to the individual, I'm sure there would be people that say something like not seeing the world isn't living and others happy to spend the vast majority of their lives in one place, is either wrong?
It's obviously tough to make sweeping generalizations about people, but if you study psychology you will learn that all humans(and indeed other animals) share certain innate drives that are part of our genetic makeup. The need for sex,reproduction,etc is one of these innate drives.
