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.
The greatest glory in living lies not in never falling, but in rising every time we fall.
Twenty years from now, you will be more disappointed by the things that you didn't do than by the ones you did do.
Exploration knows no bounds; it transcends space, time, and the limitations of the human mind.
