What do you think about long distance relationship?

Long distance, thats a tough one cause I've heard some terrible stories how people drift apart just after few months if Long distance that to years or relation comes to an end. On the other hand why not what could possibly go wrong (ik it sounds Soo easy on paper but there's something that mess that up) from my side it's like, if both are really into each other what could go wrong. Even if they drift apart this wasn't meant to be in the first place. Isn't it ??
