One possible reason why we always want more is because we seek something that is not of this world. That would be for a possible future post.
There are minimalists out there, who try to keep their lives as simple and uncluttered as possible. Here's something similar and also a little bit less work: contentment. Being satisfied with what we already have. We still work, to help others, for teamwork, to serve, but we work for a higher purpose and worry less about money. Letting money follow us instead of us following money. As to being satisfied with current possessions, we do make the most of what we already have. Using them to live healthy lives, storing them in an organized fashion so that we can find them when they are needed and not buying anything more. It would be even a good idea to have a community storage area for things that people might need, things that are in good working order, but are no longer used in the home for the past several years.
We need our health more than we need money. We think that we would need money so that we'll have enough when we get sick. But we must take care not to get sick while in the process of earning money. Choose to live healthy lives. Rest, sleep, exercise/work, healthy food. Leaving this to a possible future post.
How blessed indeed are the contented. Those who are happy where they are, and are leading productive yet unstressed lives, not always focused in the gathering of money or possessions, but of intangible things that are worth more than these. They are able to find ways to live more sustainable lives. Lives that use less resources, and yet are able to be lived more abundantly through sharing and only using things that are needed, turning off or using alternatives for things that don't have to be utilized.
