He who learns must suffer. And even in our sleep pain that cannot forget falls drop by drop upon the heart, and in our own despair, against our will, comes wisdom to us by the awful grace of God.

Aeschylus

But, in a larger sense, we can not dedicate -- we can not consecrate -- we can not hallow -- this ground.

The world will little note, nor long remember what we say here, but it can never forget what they did here.

Abraham Lincoln

Step with care and great tact And remember that Life's a Great Balancing Act Just never forget to be dexterous and deft And never mix up your right foot with your left.
