It is nothing to acquire a wealth to be happy and prosperous. However, if you going to spend you entire life just to cultivate fame or wealth, than it is not worth it. Because nobody can guarantee how long you will live and you may not have enough time to enjoy your hard work. Therefore, while, you are working, studying and serving others, you should appreciate your life and be happy for yourself and others.
