Gonna try to answer this to the best of my ability because it's such a good question, but my brain feels fried.
I feel like life is for the sake of experiencing the physical, or "real" world, but also experiencing the nonphysical, or the world beyond the physical. So a balance of physical and spiritual experience. In the world we live in today, I feel like the spiritual part of ourselves is inhibited, or put to sleep. There's so much stimulus and radiowaves interfering with our natural attunement with energies that are beyond the material world. I think that's something we lack, and perhaps one reason as to why everyone feels so purposeless and depressed (things are of course different for those who are subject to untreated trauma, etc.)
But again, I think we sort of need both? I think fulfillment through goals and trying to learn new things and create are as important in the material world as they are in the spiritual realm. I think if one is lacking, then the other might feel incomplete.
I personally think I lack in both areas, at the fault of both myself and things that are/were out of my control. Right now I'm just living to live, trying to find things to occupy my brain both passively and sometimes actively when I have the energy.
