Eureka! I have found it!
Be moderate in order to taste the joys of life in abundance.
Enjoy life. There's plenty of time to be dead.
The noblest pleasure is the joy of understanding.
Service which is rendered without joy helps neither the servant nor the served.
We are driven by the usual insatiable curiosity of the scientist, and our work is a delightful game.
I will honour Christmas in my heart, and try to keep it all the year.
There is nothing in the world so irresistibly contagious as laughter and good humor.
I must have flowers, always, and always.
