There are a couple of reasons that make Polaris, the north star, very useful.
First of all, Polaris is not DIRECTLY above the North Pole; it's about two thirds of a degree off. But that's close enough so that if we assume that Polaris is exactly above the North Pole, you won't go very far off. So if you can see Polaris, you know which direction is north.
