There are four different kinds of patience: Patience in action, in thought, in word, in the manner of feeling. There are two different acts of patience. The first is to stand firm against the activity of another person, the second to stand firm against one's own activity. Not to resist the activity of another person is an act of patience of the former sort, and to control oneself when one wishes to do or say a certain thing is an act of patience of the latter sort. The most difficult test of patience is to have to wait for something which one wants at once.
