When we focus our attention on something, we usually describe this as "centering attention on." However, there are many other synonyms which can help us to describe this action more effectively. For example, we can say that we are "focusing on," "concentrating on," or "directing our attention towards" something. Other words which can be used in this context might include "fixating on," "zooming in on," or "hom­ing in on." Alternatively, we could talk about "immersing ourselves in" or "engaging with" a particular topic or task. Whatever words we choose, the important thing is that they help us to convey our intention clearly and succinctly.
