What does a UX designer do all day?

Could you elaborate on the typical daily tasks of a UX designer? What sort of activities do they engage in to ensure a seamless and enjoyable user experience? Are there any specific tools or software that they rely on to carry out their duties effectively? I'm curious about the level of creativity and technical expertise required for this role, and how they balance the two to create optimal user interfaces. Additionally, what kind of collaboration does a UX designer engage in with other members of the development team, and how does this contribute to the overall success of a project?
