One of the 147 Delphic orders and maybe one of the most important that characterize the Hellenic way of thinking is “Metron Ariston”. This order means that being in the middle; in balance, is the best way, the top way to live.
Pythagoras, one of the greatest philosophers of all time taught this maxim as well. Pythagoras suggests for us to eat and exercise our bodies, to live a way of life in balance, to use our money with the only criterion being our true fulfillment.
Satisfaction and needs differ from human to human that's why he does not give us a 'dogmatic answer'. He focuses on the personal balance that satisfies each person within as long as he does not lack of something or exaggerate on the same thing.
We must use the observer to control how much we eat or exercise (so we are content), how we live our live (with simplicity and not exaggeration to create envy) and how we spent our money (not unnecessarily as a wasteful but also not to be stingy).
Living a life in balance with everything that creates you satisfaction and is in benefit for you and the others and always think before you act. Be the observer. In our days of exaggeration on everything we have lost the balance.
Following the advice of Pythagoras can help us live a more meaningful , happier and useful life.
