Well, that does sound a lot like what Richard came up with above:
Once you know your destination, you are already there.
But… I take that comment to be somewhat of a negative statement. As in, you shouldn’t know your destination, otherwise all of this rationality stuff is pointless. The phrase I recall (and perhaps what you’re suggesting as well) was almost more of an encouragement—like, “If you’re endlessly deliberating, it will be more useful for you to head in the direction you’re leaning vs. continuing to deliberate as if you don’t know at all.”
