Societal influences can perpetuate a culture of "shoulds" in individuals through various means. For instance, family expectations, societal norms, educational systems, and religious beliefs often dictate what individuals should or should not do. These external pressures create a sense of obligation and duty that can lead to internalizing these "shoulds." Additionally, media portrayal of ideal lifestyles or success standards can further reinforce the idea that certain actions are necessary or expected. Over time, constant exposure to these messages ingrains the concept of "should" into an individual's mindset.
