I think that it is useless to fight directly against natural weaknesses. One has to force oneself to act as though one did not have them in circumstances where a duty makes it imperative; and in the ordinary course of life one has to know these weaknesses, prudently take them into account, and strive to turn them to good purpose; for they are all capable of being put to some good purpose.
