求翻译：　　人食五谷杂粮，遇到生气是常有的事。有朋友说，如果说人一辈子遇到生气的事情，做到一辈子从未生过气，除非自身能够达到遇事不生气的境界才可。遇事不生气很难吗？不难。这个要你自己决定，选择好心情。是什么意思？

　　People eat cereals, experiencing anger is often the case. A friend said, if people encountered angry things all my life, life gas has never been born, unless itself can only reach the realm of failing to angry. Failing to angry it is hard to do? It is not difficult. This to you to decide, choose good mood.
