The best and most beautiful things in the world cannot be seen or even touched — they must be felt with the heart.
Helen Keller 的箴言
So much has been given to me; I have no time to ponder over that which has been denied.
Optimism is the faith that leads to achievement; nothing can be done without hope and confidence.
No pessimist ever discovered the secret of the stars, or sailed to an uncharted land.
We can do anything we want to if we stick to it long enough.
