Donald's two dominant personality traits are his short temper and his positive outlook on life. Many Donald shorts start with Donald in a happy mood, without a care in the world until something comes along and spoils his day. His anger is a great cause of suffering in his life. On multiple occasions, it has caused him to get in over his head and lose competitions. There are times when he fights to keep his temper, and he sometimes succeeds in doing so temporarily, but he always returns to his normal angry self in the end.
