Success is doing the best you can with what you have.

The best leaders are those who listen more than they speak.

The best way to predict the future of our forests is to create it through responsible management.

Even if it can be communicated, it cannot be understood.

乐观对于有意义的生活是无价的。坚信未来是积极的，你就可以投身于比你更伟大的事业中。
