You only live once. This life is it. There is no dread hereafter. There is no new body awaiting you after death, either on this world or any other.
But once you die, parts of you live on, embodied in the minds of others. So try to make an impression. Do your best to expand your own mind and explore the limits of your physical existence. In this way, you will live on even when your name is long forgotten.
