Hope-Have Only Positive Expectations

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.
Theory:
As specialist in positive psychology, Charles Richard Snyder studied how hope and forgiveness can impact several aspects of life such as health, work, education, and personal meaning. Snyder postulated that there are three main things that make up hopeful thinking:

Goals – Approaching life in a goal-oriented way.
Pathways – Finding different ways to achieve your goals.
Agency – Believing that you can instigate change and achieve these goals.
In other words, hope was defined as the perceived capability to derive pathways to desired goals and motivate oneself via agency thinking to use those pathways.

Snyder argues that individuals who are able to realize these 3 components and develop a belief in their ability are hopeful people who can establish clear goals, imagine multiple workable pathways toward those goals, and persevere, even when obstacles get in their way.

Snyder proposed a "Hope Scale" which considered that a person's determination to achieve their goal is their measured hope. Snyder differentiates between adult-measured hope and child-measured hope. The Adult Hope Scale by Snyder contains 12 questions; 4 measuring ‘pathways thinking’, 4 measuring ‘agency thinking’, and 4 that are simply fillers. Each subject responds to each question using an 8-point scale. Fibel and Hale measure hope by combining Snyder's Hope Scale with their own Generalized Expectancy for Success Scale (GESS) to empirically measure hope. Snyder regarded that psychotherapy can help focus attention on one's goals, drawing on tacit knowledge of how to reach them. Similarly, there is an outlook and a grasp of reality to hope, distinguishing No Hope, Lost Hope, False Hope and Real Hope, which differ in terms of viewpoint and realism.
