Be happy. Talk happiness.

The worst calamity: 'To have eyes and fail to see.'

When one door closes, another one opens, but sometimes we wait too long looking at the closed door, and never realize that another door has been opened.

My life has been happy because I have had wonderful friends and plenty of interesting work to do.

A well-educated mind will always have more questions than answers.

So long as the memory of certain beloved friends lives in my heart, I shall say that life is good.

Be not dumb, obedient slaves in an army of destruction. Be heroes in an army of construction.
