We have this obsession with having enough. I mean, I guess that's not a bad thing. There are plenty of things we need enough of to live. If we don't get enough air, we die in minutes. If we don't have enough water, we die in a few days. If we don't have enough food, we die in a few weeks. If we don't have enough shelter, we die from exposure to the elements. We're hard-wired to make sure that we always have enough for our survival, and it's a constant search for enough.
