That is, no one can prove that things are going to turn out well, nor that they are going to turn out badly. Optimism is merely a state of mind. It is a point of view. It is a temper of the spirit. And if we take this constant attitude of hope, and bright courage, it is going to make the world a better place to live in, and it is going to make us a better kind of people to live in it.
Optimism is a duty.
The Bible says, Rejoice, and again I say unto you, rejoice. It is not only a duty, it is a privilege and an advantage. It makes life easier for us, and in every way we are better qualified to get along with people and succeed in our business than those whose outlook is always gloomy.
