What you don’t know won’t kill you, but believe me when I tell you, it will definitely drive you crazy. Especially when you think you know it, but something just doesn’t seem to jell. The truth is, if you don’t know something, then you really don’t know it. And until you know it, nothing will make sense. Everything will keep confusing you, and no matter how many ways you look at it or how many strategies you use to approach it, the result will remain the same.
