The modern American economy is built on the false premise that people need to buy new goods and services all the time. Again, I call bullshit.
People need fresh air, healthy food, clean water, exercise, creative stimulation, companionship, self-esteem and a safe place to sleep.
All of these things are simple to obtain. Most of them are free.
For fresh air, go outside. For exercise, take a walk. For creative stimulation, go somewhere new. For companionship, make a friend. For self esteem, turn off your TV, breathe deep and open your spirit to the basic goodness of the world.
