Impossible

Inventors often hear:
“This is impossible.”
“It’s never gonna work.”

That’s the point — if it were already accepted as possible, it wouldn’t be called an invention.

Inventors are somewhat like mountaineers, climbing from doubt to reality, one step at a time. Their persistence turns impossibility into progress, and progress into possibility.

Soon enough, what was once unthinkable becomes:
“How has no one thought of this before?!”
