The situation with the pandemic has clearly shown that a serene life can suddenly be replaced by uncertainty and difficulties. This means that you should always be prepared for economic troubles and other unpleasant life situations. Only when we are more or less in control of our lives can we be calm.
This pandemic taught us all to be frugal at all times. Material things are not important to survive in this world but the mental strength on how to survive despite of the things that are not readily available to us. This also taught us to live simply and go back to basics. You will feel more contentment in life if there are no complexities bothering around you.
