Sight
A picture of the future specific enough to rule options out.
Most "visions" are optimism with a deadline: what you're excited about, not what you'll refuse. Sight's whole value is what it lets you decline. A direction that can't kill a good idea isn't steering anything.
The test
Name the last genuinely good idea you said no to, and why. If nothing comes to mind, you don't have sight. You have a slogan: everyone nods and no one is constrained.
