译文 ：人的思想是随着身体气血的变化而变化的。四十岁之前具有奋发进取之心，这时虽然见识不多，但是敢于闯荡一番；到四十岁以后，人的心就逐渐稳定下来了，这时已经是见多识广，而且遇到事情都会斟酌一下；六十岁之后，人的思想就开始消极保守了，这时虽然见识广博，但是精力不够。虽然这种情况不一定适用于每个人，但大体上都是如此。古代人们四十岁做官，六七十岁告老还乡，大概是因为这个原因。当然，人们中间也有年纪轻轻却思想消极，无所事事的，无精打采的就像一个垂死之人；也有一些年老之人，性情狂躁，喜欢多事，但这些都不合乎常理。如果把那些遇事风风火火的少年人当做是社会栋梁，而把那些意志消沉的衰老之人当做老成持重的话，那也是错误的。像邓禹年少时就深沉、坚毅，马援虽年老却精神矍铄的人，古代确实有过，但毕竟不是多数！

The most important thing in the programming language is the name. A language will not succeed without a good name. I have recently invented a very good name and now I am looking for a suitable language. The best way to predict the future is to invent it. The most important thing in a database is the data model. If you get the data model right, everything else will follow. The database is the most important piece of software in the enterprise, and the most important piece of software in the enterprise is the database. The database is the foundation of all applications.
