Homonym: vanity (Conceit)
Vanity is an excessive belief in one's own attractiveness or abilities. It often involves a preoccupation with appearance, leading individuals to seek admiration and validation from others. This trait can manifest in various ways, such as spending a lot of time on grooming or showcasing achievements to gain attention.

It can affect relationships and personal well-being, as those who are overly vain may struggle to connect with others on a deeper level, focusing instead on superficial qualities and perceptions.
