Psychology has many topics, theorems, and concepts that all are important in showing how humans work physically, emotionally, socially, and cognitively. I will use many things that I learned in psych for the rest of my life but something that stood out to me that I know I will remember five years from now are the Big Five traits, what they mean and how you can tell where people fall on each trait. I have always been one to analyze, especially when it comes to someone's behavior or personality. I think that by knowing the five traits (openness to experience, conscientiousness, extraversion, attentiveness, and neuroticism) I can make a better judgment of whom I will be more compatible with friendship-wise and relationship-wise. It may also help me know what certain people would do in a given situation based on where they fall in the big five personality traits. For example, if one of my friends is very low in extraversion, then I can most likely guess that she will not want to come with me to a party where she doesn't know anybody and would rather stay home or be with her close friends.
