Story of my life by Helen Keller need a quote about not giving up and explaining

When one door of happiness closes, another opens; but often we look so long at the closed door that we do not see the one which has been opened for us.

Life is either a daring adventure or nothing.

We can do anything we want to do if we stick to it long enough.

Alone we can do so little; together we can do so much.

Avoiding danger is no safer in the long run than outright exposure. The fearful are caught as often as the bold.:

Believe. No pessimist ever discovered the secrets of the stars, or sailed to an uncharted land, or opened a new heaven to the human spirit

Your success and happiness lies in you. Resolve to keep happy, and your joy and you shall form an invincible host against difficulties.

Life is a succession of lessons which must be lived to be understood.

Character cannot be developed in ease and quiet. Only through experiences of trial and suffering can the soul be strengthened, vision cleared, ambition inspired and success achieved.

What I'm looking for is not out there, it is in me.

A happy life consists not in the absence, but in the mastery of hardships.

The best way out is always through.

Never bend your head. Hold it high. Look the world straight in the eye.

The marvelous richness of human experience would lose something of rewarding joy if there were no limitations to overcome. The hilltop hour would not be half so wonderful if there were no dark valleys to traverse.

Keep your face to the sunshine and you cannot see the shadow.

Although the world is full of suffering, it is full also of the overcoming of it.

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

One can never content to creep when one feels an impulse to soar.

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

While they were saying among themselves it cannot be done, it was done.
