“Somewhere, something incredible is waiting to be known.”
— Carl Sagan
Sagan said this during his Cosmos series in 1980. He believed curiosity was not a weakness but the engine of everything. A kid from Brooklyn who saw the World of Tomorrow at the 1939 World's Fair at age five carried that sense of wonder his entire life.
I spent my whole life looking up and asking questions. Most of them never got answered. And that's okay. What matters is not the answer but the fact that you keep asking. The world is vast, and there is so much out there you haven't discovered yet. Don't be afraid of not knowing. Be afraid of losing the urge to find out. As long as you're asking questions, you're alive.
