We often find ourselves in situations that are familiar, even if what's familiar is painful.
I did what I knew to do, even when it wasn't working out because I didn't know what else to do......and it's embarassing how many years it took to get through my thick head that I could not moderate, that I can't drink just one, that I cannot drink period.
in another way-- quote from Maya Angelou which is probably mangled but you get the gist: “I did then what I knew how to do. Now that I know better, I do better.”
I agree with Chloe's comment on OpenTuning's comment above.
