• If not us, who? If not now, when?

• Liberty without learning is always in peril; learning without liberty is always in vain.

• The time to repair the roof is when the sun is shining.

• Happiness is the full use of your powers along lines of excellence.

• Forgive your enemies, but never forget their names.
