Of the countless models that examine the importance of hope in an individual's life, there are two major theories that have gained a significant amount of recognition in the field of psychology. One of these theories, developed by Charles R. Snyder, argues that hope should be viewed as a cognitive skill that demonstrates an individual's ability to maintain drive in the pursuit of a particular goal. This model reasons that an individual's ability to be hopeful depends on two types of thinking: agency thinking and pathway thinking. Agency thinking refers to an individual's determination to achieve their goals despite possible obstacles, while pathway thinking refers to the ways in which an individual believes they can achieve these personal goals.
