I've heard a famous spiritual teacher say the past is like a cancelled check and the future is not here yet. We can live with our full awareness on the present moment while at the same time consider living our lives for more than just today. Anyone who wonders where their next meal will come from or where they will sleep at night is living day to day. Most people with jobs are living month to month and spending most of what they make on expenses and saving very little if anything. Getting a financial education for most of us is learning by the school of hard knocks and there is also luck involved - who could have predicted the housing market crash? My parents taught us to be generous while also being aware of how to make and keep a buck. For years I've said at work - another day another dollar!
Over the course of a career, we've learned to spend no more than 25% of our income on housing and find ways to pay off loans as quickly as possible. I always prefer a 15 year over a 30 year loan for the lower interest rates and total savings. The real estate industry may want us to buy a larger home and spend more than we really need as they get paid by commissions. Living within our means, separating our wants from our needs, and conserving resources works for our family; however, this is not typical in the consumer society where we always seem to want more. Consider we bought our 42" flat screen TV nine years ago. It is the only TV in our home. We've been admiring all the fancy new sets with 70" curved screens as a major want but not a need - only when our TV stops working can we justify getting a new one as we are content and grateful for what we have now. One financial planner said to consider not only the present cost but also the future compound interest. For example, investing instead of buying that $1,000 TV today results in about doubling the amount at 5% interest over 30 years.
By analogy, how do we want (or need) to save and spend our natural resources? Do we want to search for water and food supplies on a daily, weekly, monthly, or yearly basis? Sustainability is really all about wise planning so we do not waste what we have and need now and not forsake our future. Perhaps society focused on consumption rather than saving for the future is great for corporate profits but not so great for future generations as populations increase and natural resources diminish. A great book on the topic is by E.O. Wilson Biodiversity Foundation who advocates we must save half of the Earth to protect many species from extinction and ultimately if we are to save humanity as well. The Hopi society promotes the idea of considering how a decision we make might affect the next seven generations. I think about all the great civilizations that have come and gone including the Puebloans, Greeks and Romans and wonder if global consumerism promoting wants will eventually be extinguished by sustainable survivalists, like the Hopi, who are careful to control what they really need.
