Helen Keller

When we do the best that we can, we never know what miracle is wrought in our life, or in the life of another.

Life is either a great adventure or nothing.

So long as the memory of certain beloved friends lives in my heart, I shall say that life is good.

Security is mostly a superstition. It does not exist in nature, nor do the children of men as a whole experience it. Avoiding danger is no safer in the long run than outright exposure. Life is either a daring adventure, or nothing.

Once I knew only darkness and stillness... my life was without past or future... but a little word from the fingers of another fell into my hand that clutched at emptiness, and my heart leaped to the rapture of living.

The best and most beautiful things in the world cannot be seen or even touched - they must be felt with the heart.

Optimism is the faith that leads to achievement. Nothing can be done without hope and confidence.
