Hope is an optimistic attitude of mind that is based on an expectation of positive outcomes related to events and circumstances in one's life or the world at large. As a verb, its definitions include: "expect with confidence" and "to cherish a desire with anticipation".

Such positive thinking bears fruit when based on a realistic sense of optimism, not on a naive "false hope".
