It is not the mountain we conquer, but ourselves.
The greatest glory in living lies not in never falling, but in rising every time we fall.
The only limit to our realization of tomorrow will be our doubts of today.
We shall not cease from exploration, and the end of all our exploring will be to arrive where we started and know the place for the first time.
To confine our attention to terrestrial matters would be to limit the human spirit.
