可持续发展不是一种选择，而是现代经济中生存的必要条件。
不存在所谓的质量问题。
All men have the stars， but they are not the same things for different people。 For some， who are travelers， the stars are guides。 For others they are no more than little lights in the sky。 For others， who are scholars， they are problems。 For my businessman they were wealth。 But all these stars are silent。 You – you alone – will have the stars as no one else has them.
写作的行为是一种乐观的行为。如果你觉得它不重要，你就不会费心去做。
