I’m hesitant to tell you that priorities come and go because that probably means that they weren’t too important in the first place. If at one point you thought sports were the most important thing to pay attention to, and later on you discover that they’re only a distraction, it was never a priority in the first place. You treated it like one! That’s dangerous, and to say that they come and go only allows for that fact. On the other hand, some things don’t have to be priorities. In fact, almost nothing you do needs to be a priority. Doing your laundry is about as close as it gets to a valid obligation. Everything else can be given up with minimal immediate consequence.
Why do you prioritize, as an example, a daily writing practice? It’s not that there are quick returns, but that there are long-term returns. Those are important, and only because you have a long-term vision for your life (somewhat) can you honestly say that such a practice is a priority today. These short-term goals have to be inextricably linked with a vision. The vision should not change. Values don’t change, either. The tasks you use to fulfill these might, and that is when priorities change—but not values. Not vision.
