[1]A long time ago, there was an Emperor who told his horseman that if he could ride on his horse and cover as much land area as he liked, then the Emperor would give him the area of land he covered. Sure enough, the horseman quickly jumped onto his horse and rode as fast as possible to cover     78   . He kept on riding and riding, whipping the horse to go as fast as possible. When he was hungry or tired, he did not stop because he wanted to cover as much area as possible. Finally he came to a point when he had covered a substantial area and he was exhausted and was dying. Then he asked himself, "Why did I push myself so hard to cover so much land area? Now I am dying and I only need a very small area to bury myself."

[2]The above story is similar with the journey of our Life. We push very hard everyday to make more money, to gain power and recognition. We neglect our health, time with our family  and to appreciate the surrounding beauty and the hobbies we love.

[3]One day when we look back, we will realize that we don't really need that much, but then we cannot turn back time for what we have missed. 

[4]Life is not about making money, acquiring power or recognition. Life is definitely not about work! work is only necessary to keep us living so as to enjoy the beauty and pleasures of life. Life is a balance of work and play, family and personal time. You have to decide how you want to balance your Life. Define your priorities, realize what you are able to compromise but always let some of your decisions be based on your instincts. Happiness is the meaning and the purpose of life, the whole aim of human existence.

[5]So, take it easy, do what you want to do and appreciate nature. Life is fragile, Life is short. Do not take life for granted. Live a balanced lifestyle , and enjoy life!
