EXO-K's Kai has this motto : I'd rather bend than break. Actually, I want to have this as my motto. I don't want to break, but I'm okay if I'm just bent.
Let's say you have a plastic ruler. It is indeed a useful thing, you can draw line and, sometimes, curves with it! This is simply because it is flexible! However, there's limit to everything. When you bend it too much, it will break. And just like this special ruler, I can break.
