As long as you are not operating it in an extremely dusty environment the majority of the time, it’s probably not a huge deal to go all out on getting fixed. That is assuming it is a vacuum leak.
If you were in a dusty environment most of the time, like West Texas for example, I would say the sooner you can fix it (again, assuming it is a vacuum leak) the better. Otherwise it can slide down the list of priorities for things to spend money on fixing or maintaining on the car.
