“If you don't know where you are going, how will you know when you get there?”
“If you don’t know exactly where you’re going, how will you know when you get there?”
“Unless you know where you are going then you will not know how to get there.”
“If you do not know where you come from, then you don't know where you are, and if you don't know where you are, then you don't know where you're going. And if you don't know where you're going, you're probably going wrong.”
“It is important that we know where we come from, because if you do not know where you come from, then you don't know where you are, and if you don't know where you are, you don't know where you're going. And if you don't know where you're going, you're probably going wrong.”
“Things start where you don't know and end up where you know. When you know is when you ask, How did this start?”
