driving myself crazy....

ok, i am not one that has this compulsive instinct about matchy/ matchy...in fact, i am far from that. but i am driving myself crazy trying to figure out if i feel like the lighting, hardware, and plumbing fixtures have to match....like do you think that if you have oil-rubbed bronze lighting and hardware, then should your plumbing (faucets, shower heads, etc.) be the same or are you at peace w/ making them something completely different like satin nickel?? i don't feel like in a house you have to be alllll one way or the other but in a space/ room i'm torn....
