Be content with what you have
It was Lao - tzu the person who said: "Be content with what you have; rejoice in the way things are. When you realise there is nothing lacking, the whole world belongs to you".
Obviously, we live in the XXI century and lots of things have changed in the world since Tao-tzu lived. Nowadays, we can't imagine a world without international organizations collecting money, food, medicines and the like to help people all over the world. However, his words focus on the idea that we should look for simplicity in our lives in order to find truth and freedom.
He is also thought to have said: "Give a man a fish and you will feed him for a day. Teach him how to fish and you feed him for a lifetime".The main idea is that humans can obtain respect by doing their best "to fish" rather that accepting "fish" as charity. Tao-tzu also points at the importance in understanding the laws of nature to develop intuition and build personal power in an attempt to live a live full of love and sense.
Tradition says that he was so sad by the things he saw around that he left civilization and went to the desert on the back of a buffalo. As he approached the Great Wall gate, the gatekeeper urged him to stay and write his beliefs for future generations.
The 81 chapters of what we know now as the Tao-te--ching is one of the most translated texts after the Bible. Besides, some of his best quotations can be easily found in management textbooks.
