The principal thing in this world is to keep ourseles happy. We should have a good temple because the bad temple aggravates the situation . Chances of surviving an adverse environment always show appreciations for those who can adapt better to it . Nowadays people have many things unhappy such as the rising prices and the lower pay . Recently I spent my time in studying the stock market and preparing my CET6 . I even have the graduation design about the stock forecast  by using neural network . It makes sense to try new options as they may prove adventageous in the long run. Hope I can do it well .
