Never sell the bear's skin before one has killed the beast.

Habit, to which all of us are more or less slaves.

All the brains in the world are powerless against the sort of stupidity that is in fashion.

Be advised that all flatterers live at the expense of those who listen to them.

Everyone calls himself a friend, but only a fool relies on it; nothing is commoner than the name, nothing rarer than the thing.

You've tried to reform what will not learn. Shut doors on traits that you wish were dead; They will open a window and return.

In everything one must consider the end.
