Never measure the height of a mountain until you have reached the top. Then you will see how low it was.

Never look down to test the ground before taking your next step; only he who keeps his eye fixed on the far horizon will find his right road.

Pray that your loneliness may spur you into finding something to live for, great enough to die for.

Never, 'for the sake of peace and quiet,' deny your own experience or convictions.
