The great thing is to know when to speak and when to keep quiet.

Conversation has a kind of charm about it, an insuating and insidious something that elicits secrets from us just like love or liquor.

We ought to take outdoor walks, to refresh and raise our spirits by deep breathing in the open air.

Let the man, who would be grateful, think of repaying a kindness, even while receiving it.

Let ease and rest at times be given to the weary.

My joy in learning is partly that it enables me to teach.

What a great blessing is a friend with a heart so trusty you may safely bury all your secrets in it.
