Final answer:
The individual who can't go 10 minutes without looking at themselves in the mirror is most likely a narcissistic person. This behavior is characterized by an excessive preoccupation with oneself and their physical appearance, which differs from self-efficacy, a positive belief in one's capabilities.
Step-by-step explanation:
The question surrounds a particular behavioral trait that is often associated with one's attitude towards themselves. Based on the question, the person who can't go 10 minutes without looking at themselves in the mirror is very likely a narcissistic person. This term is used to describe someone with an excessive focus on themselves, particularly their physical appearance. They may exhibit traits that involve a high level of self-admiration and an inflated sense of self-importance.
In the context of confidence in one's abilities, the term that is mentioned as known for that is self-efficacy. This refers to a belief in one's ability to succeed in specific situations. It's important to note the difference between narcissism and self-efficacy, as the former is often considered a negative trait associated with an excessive preoccupation with oneself, while the latter is regarded as a positive and realistic understanding of one's abilities.
An egocentric person, on the other hand, might also demonstrate similar behavior to that of a narcissistic person, as egocentrism involves an inability to distinguish between self and other. However, egocentrism is not the direct answer to the question that was asked.
