No, I'm saying what specifically could it do
Say if you cast a protection spell on yourself, and like, a car door got shot off from an accident and was heading towards you (unlikely premise, but work with it), and a gust of wind suddenly picks up on a clear, calm day that diverges the path of the door juuust enough so it misses you by a few millimeters. You could say the protection spell caused the wind to pick up, since it probably wasn't going to be a very common occurrence on a calm day like that.
How would a spell help you get a job? Is there really anything it could specifically do other than just increase your luck or something?
