We are standing on the shoulders of giants, but there is still so much more to discover.

True progress is measured not just in profits, but in positive impact.

Knowledge is a consequence of experience.

可持續性不僅僅是一種趨勢，更是我們對后代的責任。

每個孩子都應該玩泥餅、捉蚱蜢、玩水蟲、養蝌蚪、抓青蛙、玩泥龜、采接骨木果、摘野草莓、撿橡子、采栗子、爬樹、涉溪、賞睡蓮、觀察土撥鼠、蝙蝠、蜜蜂、蝴蝶，養各種小動物，在干草場玩耍，撿松果，滾石頭，玩沙子，抓蛇，采越橘和胡蜂窩；任何被剝奪了這些樂趣的孩子，都被剝奪了教育中最美好的部分。
