In this continual battle of life the one who stands firm through it all comes out of it victorious in the end. Even with all power and understanding, if one gives up through lack of hope and courage, one has failed. What brings bad luck in this life, in this battle, is a pessimistic attitude; and what helps man to conquer in the battle of life, however difficult, is an optimistic attitude. There are some in this world who look at life with a pessimistic view, thinking that it is clever to see the dark side of things. To some extent it is beneficial to see the difficult side also, but the psychological law is such that once the spirit is impressed with the difficulty of the situation it loses its hope and courage. Once a person asked me if I looked at life with a pessimistic attitude or if I was an optimist. I said, "An optimist with open eyes." Optimism is good as long as the eyes are open, but once the eyes are closed then optimism can be dangerous.
