The wise does at once what the fool does at last.
Never have a companion that casts you in the shade.
To find one real friend in a lifetime is good fortune; to keep him is a blessing.
When everyone covets something, they are easily annoyed by it.
No one demands more caution than a spy, and when someone has the skeleton key to minds, counter him by leaving the key of caution inside, on the other side of the keyhole.
There is no desert like being friendless.
