The psychological capital is one of the greatest challenges to researchers that try to investigate the positive aspects of human prosperity, motivation, and performance. The construct is conceptualized as four dimensions: self-efficacy, resilience, optimism, and hope. This chapter will approach the last two dimensions: optimism and hope. Optimism refers to positive thoughts that generate positive expectations to the future and will be approached under to investigation lines: learned optimism and optimism as prospection. Hope, understood as the belief that one has willingness to reach goals, has brought about investigations that differentiate pathways-based hope and agency-based hope. This chapter will also approach the pathways of constructs in investigations, their instruments of measurement, and the practical implications that could contribute to the development of optimism and hope in corporate environments.
