There is at least one thing that you don’t know.
Since you’re unaware of what that one thing is, then you have no idea how important it may be.
If you knew what you don’t know, your current understanding of what you do know might be entirely different from what it is.
For all you know, today’s “knowledge” might be tomorrow’s punchline.
Here’s today’s two cents:
Remain open to the possibilities inherent in what you don’t know.
You haven’t tried everything. You haven’t seen it all.
Whatever it is that you think you know, hold on to it lightly. Because at any given moment, the unknown could tap you on the shoulder and completely revolutionize your understanding of the universe.
