实现明天的唯一限制是我们今天的疑虑。
The only limit to our realization of tomorrow is our doubts of today.
Don't watch the clock; do what it does. Keep going.
The only way of discovering the limits of the possible is to venture a little way past them into the impossible.
Life is too short to wake up with regrets. So love the people who treat you right, forget about the ones who don’t, and believe that everything happens for a reason. If you get a chance, take it. If it changes your life, let it. Nobody said life would be easy, they just promised it would be worth it.
The best solutions often come from those who work closest with the animals.
"A good picture book is like a silent movie; it tells a story without words."
We don't inherit the earth from our ancestors; we borrow it from our children.
可持续发展不仅仅是一种趋势，更是我们对后代的责任。
La poesía es la única prueba concreta de la existencia del hombre.
