We don't inherit the earth from our ancestors; we borrow it from our children—this is especially true in forestry.

We tend to overestimate what we can do in a day， and underestimate what we can achieve in a decade. Miraculous things can be accomplished if you give it ten years. A long game will compound small gains to overcome even big mistakes.

你的努力（锻炼、陪伴、工作）的一致性远比数量重要。没有什么可以击败每天坚持做的小事，这比偶然做的事情重要得多。
