Answer:
ideal
Step-by-step explanation:
In psychology, the ideal self is a personality domain that refers to "Who I want to be" as opposed to the "real self" which refers to "who I am". As individuals we are often trying to make the gap between the real self and the ideal self smaller in order to feel good with ourselves.
In this example, Andy has always wanted to be a part of the college football team and he attends all the trials and works hard to maintain his fitness. Since being part of the team is something that Andy wants to do, and wants to be, we can say that this appeals to Andy's ideal self.
