不要把名字写在沙滩上，海浪会冲走它。不要把名字写在天空中，风可能会吹走它。把你的名字写在人们心里，那里才是它永存的地方。
Don't write your name on sand, waves will wash it away. Don't write your name in sky, wind may blow it away. Write your name in the hearts of people, that's where it will stay.
The future of forestry belongs to those who see trees as living systems, not just standing inventory.
