I refer to it often. Many times problems will resolve themselves if you don't just do something. Furthermore, simply sitting there, even if only for five minutes, will help you get centered, gather information, and ultimately take an action that's considered and useful as opposed to hysterical and reactive.
Reducing consumption and saving energy naturally arise from this policy. If you don't just jump up and drive your car to the store to fix your latest problem, craving or anxiety, you will save gas and resources. If you sit there and don't buy a car for a few years, you save money and reduce consumption of new cars. Sitting still is good for your psyche if you're practicing your breathing meditations; it's also free and carbon-neutral.
