At any given moment, how do you decide what you will do? Maybe you will read a book, or play music, or pay bills, or make a meal. To help you with that decision, you might have an explicit (or maybe just a subconscious) list of priorities.
Setting priorities can be a tricky thing. You need a mix of short-term, medium-term, and long-term tasks or goals, and you might need to have some time set aside for no goals at all, for pure recreation or to recharge. But how do you determine what is most important, and how does that change from moment to moment?
