Silence is the sanctuary of prudence.
Hope has a good memory, gratitude a bad one.
To keep is more important than to make friends.
Harness the imagination, for she is the whole of happiness.
True friendship multiplies the good in life and divides its evils. Strive to have friends, for life without friends is like life on a desert island... to find one real friend in a lifetime is good fortune; to keep him is a blessing.
You have to appear wiser and more prudent than is required by the people you are dealing with if you want to give a high opinion of yourself.
