What every living thing seeks. Survival because death is an unknown for those of us who are sentient, and the end of the opportunity to procreate for those of us who are not. Well-being because plain ol' survival isn't necessarily pleasant nor enjoyable. No, most of need a place for all of our stuff, something to do, something to look forward to, someone to share it with, some sheer aesthetic pleasure here and there, an influx of knowledge, and enough sleep to feel good for our well-being.
