Uses of Pronouns
We use pronouns so we don’t have to repeat the noun; it makes it sound a little better when we’re talking about one subject for several sentences.
When Michael first started Michael’s new job, Michael was a little apprehensive. After all, Michael had just finished Michael’s post-secondary education, and Michael suddenly felt Michael hadn’t learned anything about the real world.

You can see how the use of pronouns makes the paragraph sound less repetitive. Notice, though, that Michael’s name has to be mentioned at the beginning of the paragraph; otherwise, we wouldn’t know which man was being discussed.
Pronouns can be subjects or objects, or show possession.
Pronouns can also be used to name something unknown or unspecified: someone, something, anyone, anything, etc.
Someone is up to something here; I just know it.
