The psychological effect of optimism is such that it helps to bring success, for it is by the optimistic spirit that God has created the world. Optimism therefore comes from God, and pessimism is born out of the heart of man. From what little experience of life he has man feels, "This will not be done, that will not succeed, this will not go, that will not come right." For the optimistic one, if things will not come right in the end, it does not matter; he will take his chance. And what is life? Life is an opportunity. To the optimistic person the opportunity is a promise, and for the pessimistic person this opportunity is lost. It is not that the Creator makes man lose it, but it is man who withdraws himself from the possibility of seizing the opportunity.
